The moment I saw this fabric I knew it had to transform into a backpack. I waited for some time before actually having the courage to cut it, but in the end I was happy I did.
The fabric is awesome, it looks like cotton on the outside but it’s stiff and impermeable on the inside. Looks like cotton, behaves like oilcloth? Magic.
I made up the pattern looking at an old backpack I had in the house. I also reused the straps because they were in perfect state. For the back part of the backpack I used quilt batting.
Since the fabric was stiff enough I didn’t have to use lining, so sewing the whole thing was pretty easy. Way easier than I expected.
