I found this on pinterest and I found it quite interesting. I was originally looking for a sole for a knitted slippers, so I thought to give it a go.
It was quite easy to do it, once you get the trick and got it right. I was quite amused in the process, but you have to be patient. For me it was a trial, so I put middle effort on it.
It is really comfy, but if you want them for flip flops you have to give them a more hard structure, wire maybe? But as in my case I was looking for a sole for a slippers project, it might work. I have to work out how to saw the wool yarn in the t shirt yarn… that will be a challenge. So let’s give it a go!^^
