This is a follow up post to my previous one. I am answering my question about how this wool reacts to felting as a single strand.
I made a coffee cup cozy. I just used St St for the circumference of my coffee cup.
I used as single strand of Bernat Felting Natural Wool and felted it twice as I did with the pot holder.
This method showed a lot more shrinking than the two strand method. I will enjoy this cool cozy to hold my hot tea cups.
I did both of these experiments to prepare for a pair of felted slippers that I am making for Alex. I will post on them in the next few days as I finish them up.
