What you see here ist a Makeup bag made entirely from plastic bag fabric that I found on craftster.org. The one who made the bag links to the tutorial on how to make sewable fabric from plastic bags.
Once I tried this technique but it didn’t work as supposed. I think I put my iron at a too high temperature. Or possibly the bags I tried to fuse were made from different plastics and therefore incompatible.
I will try it again – one day soon ;-)
