@Lowena, I used 2 different methods to make the bags, but both use wadding and/or stiff interfacing. I used and modified existing tutorials online, but Imi has been ‘encouraging’ me to put up my own tut of how I made them. I am busy for the next few days, but if you can wait, I’ll see what I can do. I am a complete novice at tutorials!
Imi has even suggested a possible bagathon - so possibly more to follow if people are interested.
