After making all the bags mentioned in this post I had a go at designing and making one. Its a small bag (approx. 7 X 7'') with a long strap (45'') so it can be worn across the body (hands free). There is a zippered pocket at the back to keep valuables safe. For the front flap closure I used a magnetic snap and for the interfacing I used craft-fuse Pellon style #808 .
Bag fever continues, this week I brought a new book called "The better bag maker" I am currently reading it so expect more bag stories soon.
Have a good one!
