Make your own knitting bag: part II

Here's the promised part two on how to make your own knitting bag. I've never made a bag like this before so all my instructions are from what I worked out by looking at other bags. So you may have a different (and likely more logical and simple) way of doing things so ignore me on those bits. And do post your method - I'd love to hear!

First, make your bias binding for your piping. Skip this section if you know how to do this. I have a foolproof method for finding the bias using a simple piece of kit. Some people use bias binding makers; I have no idea how to use one of these. Instead, get hold of a set square or 45° (or even a protractor) triangle ruler. If you don't have one of these I'd recommend getting hold of one they're also useful for making 90° angles, so cutting straight across the weft threads, say if it was cut wonky off the bolt at the fabric shop. I bought a set with a large ruler, large 45° and 60° triangle rulers and a large protractor for under £5 and it was money well spent.)Simply line it up your triangle with the warp threads, you can use the selvedge if you like, and then rule along the diagonal edge. Then I use an ordinary 30cm ruler as it's about the right width for bias binding to make further lines--



Sew these strips together, pinning them at 90° angles--




Press the seams open. Lay your piping down the middle of the wrong side and pin the fabric together perpendicular to the cord. With a piping foot, sew close to your piping, but leaving a little breathing space - and don't sew into the piping! Here are the diagrams for reference again--




Cut medium to heavy weight interfacing (depending on the fabric you are using) for pieces except piece 5. Using a steam iron press onto wrong side of fabric.

Mark the centre point of the length and height of piece 1. Mark the centre point of the length of pieces 3 and 4.


Take two small square scraps of your fabric and press one edge for a quarter inch seam allowance. Pin the folded edge over the ends of your zip so that they will fall about 1cm within the finished length of your bag. (The photo is a close up after the next step but you get the idea.) So for my bag I had 38cm of exposed zip for a finished length of 40cm. Sew these onto the zip by sewing perpendicular and to the zip close to your folded edge. You may have to turn the wheel by hand as even with a long stitch length the needle can hit the teeth.

Centre zip onto piece 2b and pin. Sew using a zip foot; no need to get really close to the teeth. A little strip of exposed zip tape looks quite nice when you use the big chunky zips. Press flat, being careful not to put your iron over the teeth - they'll melt so watch out. Now line up the raw edges of piece 2a with 2b and pin onto zip and sew in the same way. Together this piece is now piece 2.

This is how things look so far--





Mark the centre points of the height and length of piece 2.

Now take your two 2b lining pieces. Turn the above to the wrong side. Pin one of the lining pieces to seam on what was piece 2. Now sew about 3mm outside of where you sewed the zip onto the outside pieces.







Now do the same but pin and sew the other pocket piece onto the other side of the zip. Press. Then using a 1cm seam allowance sew the two pocket pieces together, going up as far as you can toward the zip.



Now attach the piping to pieces 1 and two with your zip/ piping foot. Clip the piping at 1cm intervals round the corners just before you get to them. Leave about 2" - 3" unsewn at the bottom in the middle. Then cut your piping leaving a 1" overlap. Unpick the stitching on the piping about an inch on each end. Then pull out the exposed ends of your cord and trim a half inch of each so that they lay flat and do not overlap but touch each other. Then fold one exposed end of your piping fabric over and finger press. Lay the other side of your fabric with the raw edge inside this one. Push the cord into the channel and using your thumbnail nicely smooth it in so those open edges don't fan out. Pin perpendicular to the piping Now sew along to close up this final part of the piping.




Now sew the longer zip onto pieces 3 and press.



Attach piece 4 onto the open end side of the zippered pieces 3 (the one you see in the picture). Press seam towards piece 4. Topstitch. Lining up the centre of the long side of piece 1 and the centre point of zippered piece 3 just check that the seam is in line with your centre point and that the on your raw edges of the zippered and bottom piece extend 1.5cm respectively from the centre point of the height of your bag. If not work out how much you need to add or subtract from your seam allowance Repeat sewing and topstitching for the other side.

Starting at the centre point of the shorter side of piece 2, wrong sides together, start sewing one side of piece 3 on. You will be catching the pocket lining as well so make sure this stays flat and smooth. You need to decide which direction you want the zip to open in, i.e. left to right or right to left. Clip seam allowance of pieces 3 and 4 as you  get to the corners to make sewing easier. Also try to stay as close as possible to the piping without sewing through it. On the corners you will need to keep the needle down, lift the foot and rotate.

Then do the same for piece 1 and the other side of your zippered pieces 3 and piece 4. Trim down the seam allowances.

Now for the handles. With wrong sides together sew one piece of interfaced fabric and one piece of contrast fabric of pieces 6 together using a 1/4" seam allowance. Sew both long sides and one short side together. Clip corners diagonally and turn through. Press. Repeat. On the open ends fold the raw edges inside about 1/4".

Determine how far apart you want the handles to be. I made mine 11cm apart to the outside edges. Centre over your pieces 1 and 2 with the contrast side underneath. I doubled the ends over about 2cm for extra stability. Place the fold 2.5cm from the piping and push the seam allowances in the bag towards the zip. Sew a rectangle and cross through the diagonals being careful not to catch the piping.


Next time I'll finish by showing how to make the lining...

Make your own knitting bag

I’m always carrying my knitting to my boyfriend’s place in plastic bags (rocking the bag lady look) that inevitably get punctured on the journey. Once the bf stuck his hand in my bag and yelped after he accidentally palmed the sharp end of a knitting needle. It was time, I decided, to make a knitting bag.

And here it is--









The bag is 40 x 10 x 15 cm. It has contrast piping, a contrast inner wall and contrast backed handles. Only the contrast piping was planned; the other pieces were cut from the yellow fabric when the blue ran out. I hadn't bought any of the fabric with the bag in mind! There is an outer pocket, lined in another contrast fabric (also an improvisation when the blue fabric ran out), and two inner pouches which are slightly elasticated to hold bulkier items in place. In the final photo you can see the scarf I've been knitting recently!

Pattern
I have not put measurements on the pattern in case you want to make your own. My needles are 35cm long so this was the rationale behind a length of 40cm. Also the wool I use comes in smaller balls and my projects are scarves, not jumpers, so my bag didn’t need to be too tall or deep. In case you want to make yours the same size, here are the dimensions, all in cm with 1.5cm seam allowance:


1.   FRONT                                  43 X 18
2a. BACK ABOVE POCKET          43 X 6
2b. BACK BELOW ZIPPER           43 X 15
3.   BOTTOM                               56.7 X 7.5
4.   TOP                                       56.7 X 13
5.   INNER POUCH                        47 X 14.5
6.   HANDLE                                 30 X 3.5 (0.5cm or 1/4" seam allowance)


**If you're making your bag to custom dimensions and don't want to do all the maths yourself, here's how to calculate the length of pieces 3 and 4.

Draw a small square in each corner of piece 1 and the top and bottom corners respectively of pieces 2a and 2b (mine were 3 X 3cm). Use this to draw a curve with a compass or eyeball it. We will use the rule circumference = 2πr in a sec. [If you don't have a scientific calculator, pi is 3.142.]

- Calculate the total perimeter including seam allowances of your bag front. I will use my bag as an example. eg. 122cm

- Subtract twice the perimeter of your corner square. eg. 3+3+3+3 = 12, 12 X 2 = 24 so 122-24 = 98

- Now drawing that square becomes relevant. To find the length of the curves at the four corners (four quarters of a circle!) multiply the length of one side of your little square by 6.284 (which is 2π), eg. 6.284 X 3 = 9.42. Add this onto your total perimeter minus corners eg. 98 + 9.42 = 107.42.

- Now divide this by two. eg. 107.42 / 2 = 53. 71 Add on seam allowances, eg. 56.71, and you're done!**

Materials
For the dimensions I have given you will need:
1/2m of heavy weight fabric such as canvas, twill, denim, oilcloth or any upholstery grade cotton. I used normal medium weight cotton and even with heavy interfacing it is quite flimsy.
0.4m medium weight fabric for lining (quilting cotton, poplin, lawn)
0.2m contrast medium-weight fabric (for the piping and inner contrast wall)
0.15m second contrast medium-weight fabric (for the outside pocket)
1/2 heavy iron-on interfacing
2.3m thick cording (nylon is preferable) 
45cm zip
60cm zip
40cm 3mm elastic
Polyester thread

Heavy weight fabrics machine needle (blue or size 90/14)
Zip and piping foot


Next post I'll tell you how to make the bag as this one is getting long...
