I want to make some wool flannel covers with some wool flannel I bought. How do I prep this? Do I need to felt it? I have seen some that are felted, but most of the commercial ones do not seem to be felted.
I think it's up to you. I made a few diaper covers from wool flannel shirts I found at goodwill. I did felt them beforehand, but it really didn't change the flannel that much, as the weave was already very tight. I thought if they were felted right from the start they might do better being machine washed on delicate). I think the main thing is just to lanolize whatever you make.
