A step too far?

I have decided to make these felted slippers by French Press Knits

I have never felted before so I’m a little concerned that things will not quite go as planned and I end up with some rather strange footwear!

I popped into my (not so) local yarn store to get some wool. They didn’t have exactly what I was looking for so offered me ggh Bel Air as an alternative. It’s 90% merino wool and 10% nylon so I’m not too sure that it will actually felt (should I not be using 100% wool???). However when I was presented with this colour I just couldn’t resist….

Maybe I should have gone for something a little less ‘obvious’?
