I have been meaning to do this for so long, and I am so pleased I have finally made some felted insoles!
I started off with two rectangles, made in double crochet, put them through the washing machine at 40 degrees C along with the household wash, and then cut the felted pieces with scissors using a pair of existing insoles as a pattern.
My rectangles were between 21 and 25cm x 20cm before felting, but I would say 25cm x 15cm would be ideal. I am a size 5 shoe so you might want to increase this for a significantly larger shoe size. Because I used aran thickness wool I would say these insoles are too thick for a normal shoe, but they are in my Wellington boots just now and are so cosy!
Made in Drops Alaska Dark blue (37), Navy blue (12), Denim blue (57) and Mustard (58) on a 6mm hook. You might remember that this was originally a colour scheme for a hot water bottle cover – so please note: these hot water bottle covers are not machine washable!
