I do need to adjust the fit. I didn’t sew the sides tight enough (and I might add some elastic to the back too to make sure they don’t slip).
They’re a surprisingly easy and quick project. The video that The Makery did on Youtube was very useful to watch too. I’d add that you need to be extra careful you sew through all the layers of fabric where they overlap! I missed a bit of the inner fabric on the first shoe I made.
All you need to be able to do is a bit of blanket stitch!
Also you will need a lot of pins!
