This is a tutorial on how to make the small triangle bag. The bag is perfect for your sock-knitting or quilting supplies.
What you need is:
Your sewing machine and sewing supplies like: needles, thread so on..
Outside fabric: 35 x 25 cm (14 x10 inch)
Inside fabric: 35 x 30 cm (14 x 12 inch)
A zipper that you can take apart that is 27 cm (11 inch) long.
Optional: interfacing so you can make your bag more sturdy. I used a light one since I use the bag to take with me in my handbag and I don't want it to get too heavy.
Attach you interfacing on the outside fabric. Cut your inside fabric into a 35 x 25 cm piece (14 x 10 inch). (The leftovers will be used later) Cut your inside and outside fabric in 2 pieces. So you will get 2 pieces that are 17,5 x 25 cm (7 x 10 inch) of the outside and inside fabric.
Mark your outside fabric by laying your fabric on your work surface putting the 2 pieces together which you just have cut apart. On the cut make a mark 1.5 inch inwards on each side like in the picture above.
Take your zipper apart and put it with the "teeth" of the zipper on the fabric facing down and pin it in place. Do the same with the second part of the zipper. (see photo)
From the leftover piece of the inside fabric cut 2 rectangles that are 5 x 7.5 cm ( 2 x 3 inch). Fold this so you will get 5 x 3.75 cm (2 x 1 1/2 inch) pieces.
Open the 2 fabric pieces with the zipper and finger-press it so that it looks the way it should. Now put the zipper-pull back in. Hereby creating one big fabric piece with a zipper in the middle.
After you have put the zipper-pull in you will have room between the edge of the fabric and where the zipper is sewn in. Slide the 2 pieces of folded fabric in and pin it into place.
Sew a nice seam over the zipper and by doing that sewing the folded fabric in.
So now you should have a piece of fabric with a zipper in the middle.
Fold the fabric: right sides together of the outside fabric and the right side of the inside fabric on each-other. Like in the picture. Sew around the 2 short sides and on long side. So 3 sides only..not all 4 sides. (don't mind the marked square in this picture it will be explained in the next step)
Mark a corner 6.5 x 6.5 cm ( 2,5 inch) as in the picture and cut it out. You need to cut out 2 corners opposite of each-other. These corners are the corners that are sewn. So one corner of the outside and one corner of the inside fabric) You still have one side of the bag that is not sewn.
The last 2 steps are shown in these clips because you need to turn the fabrics different ways which is hard to explain in just text.
You will take the left-over piece of the inside fabric and fold it so you will get a nice piece of fabric to put over the last sewn seam like in the picture.
I hope this is clear enough so you can make this nice triangle bag!
