When I first decided to make a snap bag, I made the most simple one possible. It’s really more of what I would call a purse, but it was such fun that it gave me the impetus to go and make another slightly more elaborate snap bag.
For this version of the snap bag I cut two 11″ by 8.1/2″ pieces of fabric in both the top fabric and the lining fabric. With right sides together and using a 1/4″ seam, sew together three sides of the two top fabric pieces to create a pounch shape. Sew together two sides only of the two lining fabric pieces to create a tube shape. With right sides together pull the lining fabric tube down over the top fabric tube and line up the top edges.
Sew a 1/4″ seam around the top edge so that you are joining the two tubes to each other. Pull the snap bag lining fabric tube up so that it is stretched out above the top fabric tube as shown. The opening is at the top left of the photo, at the end of the blue lining fabric.
Meanwhile cut two 10″ lengths from an old metal measuring tape. Remember to lock the tape measure so that you don’t lose the end inside the body of the tape. Round the edges and wrap in insulating tape or something strong that will cover the sharpness of the end of the tape and stop it cutting the snap bag fabric – or you!
With the snap bag lining still extended, place one length of tape just below the seam and with the numbers facing towards you. Underneath it place the second length of tape with the numbers facing away from you. Sew a small hem across the bottom of the lining fabric and push the lining down between the two lengths of tape so that it is in position inside the bag and two lengths of tape are trapped between the lining and the top fabric of the bag. Pin.
I had intended to machine sew above and below the tape to hold everything in place but this proved very difficult so I used embroidery thread to hand sew a line of running stitch above and below the tape to hold it in place. That completes the snap bag and you’ll find that it gives a very satisfying snap as the bag opens and closes.
