This is my lovely and very colourful new bag I’ve made for work. I thought I’d share how I made it in a tutorial. It’s going to be pretty picture heavy as I find it easier to follow pictures.
To make this bag I used 4 fat quarters from Japan Crafts, which you can find here. They also do kits if you prefer.
As well as the fabric you need matching thread, a 20cm minimum zip, magnetic snap fastener, medium weight iron on interfacing, iron on wadding. You will also need scissors, a tape measure, pins, pliers, double sided tape and a sewing machine. Before you start please read through to make sure you understand all the instructions.
Step 1
Make a paper template for the bag 37 cms wide, 32cm high at the sides with 72 cm in the middle for the strap. The strap is 7cm wide and I made the curves using a dinner plate. This includes a 1cm seam allowance all round with a base of 10cm wide. As I was using fat quarters I had to cut an extra strip from the side to make the strap long enough. I don’t have a picture of my pattern, but I hope it’s clear what I mean from this picture. Don’t forget to add in a couple of centimetres if you have to piece the strap for the seam allowance.
Step 2
You will need to cut 4 pieces using this pattern, 2 for the outside and 2 for the lining. Also use the pattern for 2 pieces of interfacing and 2 pieces of fusible wadding.
From the remaining fabric cut 2 rectangles 25cm x 18cm and 2 of interfacing for the internal pocket. Also cut 2 rectangles of fabric 26cm x 18cm for the zip pocket and 2 of interfacing.
Step 3
If you need to, stitch the straps on to the bag pieces, and iron the seam open. Now iron the interfacing to the back of the outer fabric. This always seems to take ages. Do the same with the wadding on the lining. This takes even longer. Iron the interfacing on the back of the pocket pieces.
Step 4
Now stitch together the body and lining down one side and iron the seams open.
Step 5 – zip pocket
The zip needs to be at least 8cm shorter than the width of the pocket so trim it to size from the pull side then stitch the ends together.
Measure the length of the zip teeth and the draw a rectangle 1cm wide and the length of the zip teeth (the bit that will show on the outside ).
Position the rectangle at least 5cm down from the top of the pocket.
Place your pocket on the front of the bag right sides together making sure it is placed centrally over the seam and at least 7cm down from the top of the bag. Stitch round the outside of the rectangle.
Now using sharp scissors cut along the central line and into the corners carefully. Don’t snip your stitches.
Now pull the pocket through the hole to the back and iron carefully.
Now here comes the double sided tape. Cut a couple of strips and use them to stick the zip to the back of your opening. Try and get the tape near the edges so that you don’t stitch over it and gunk up your needle.
On the front stitch round the opening using a zip foot and then take out the tape.
Finally, pin the other pocket piece to the back of the pocket with right sides together. Now sew round the outside and voila, you’ve made a lovely flush zip pocket.
Step 6 – internal pocket
Take the other 2 pocket pieces and pin them together right sides together. Stitch round the outside leaving a gap of about 8cm along the bottom edge. Clip the corners and turn it through to the right side then iron carefully.
Then stitch close to the top edge. Pin the pocket to the lining centring it on the seam 7cm below the top edge and stitch close to the edge down the side, along the bottom, closing the opening and up the other side. Then stitch a seam down the middle to make 2 pockets.
Step 7
Line up the remaining sides on the outer fabric and lining and stitch closed.
Step 8 – magnetic fastener
On the lining mark where the fastener will be 4cm down from the top. I used the plate that goes on the back to mark where to position the snap.
Make 2 little snips and push the legs of the snap through. It’s a good idea to reinforce the back with an extra piece of interfacing before pushing the plate over the legs. Take your pliers and bend the legs in.
I use a scrap of fabric over the front of the snap to protect it. Repeat on the opposite side making sure the 2 halves match up.
Step 9 – the base
Line up the bottom edges of the bag with the right sides together and the seams lined up with each other. Sew along the bottom.
The next bit is a bit tricky to explain, but hopefully the picture clarifies it. At the corners squash it together to make a triangle.
Draw a 10cm line across and then stitch it. Cut off the excess and repeat at the other end. It creates a square base. Repeat with the lining, but leave a gap of about 10cm in the middle of the base for turning the bag right side out later.
Step 10
Turn the lining inside out and push the outside of the bag into it so that the right sides are together. Pin the top edges together.
Stitch around both sides leaving 6 to 8cm free at the top of the straps.
Clip the curves.
Step 11
Pull the bag through to the right side through the hole in the lining.
This is quite hard to do and when you get to the straps it can be a job to pull them through. I used this tool to help.
I got it from a market years ago. I think it may be a medical tool. (Swab please nurse). Pliers would probably work as well.
Now iron the bag, paying special attention to the edges.
Step 12
Line the straps up with right sides together and stitch together.
Repeat with the other side. Iron seams open and then turn sides under. Now topstitch around both sides close to the edge closing in the raw edges on the strap.
Almost done. All you have left to do is to sew up the lining. I used a ladder stitch, but you can machine it closed if you prefer.
Doesn’t that look neat?
Finally, iron your bag and admire.
Look at that loveliness inside that pocket, and so useful too.
And another useful pocket, perfect for a phone or my glasses.
Well, that’s it. I hope it’s all clear. If you have any questions just ask and I’ll do my best to help.
