I used Chocolate Peruvian Felting Wool and Cream Misti Alpaca.

I love the way these felted!

I purchased suede bottoms from Webs (instead of sewing suede circles to the sole as recommended by the pattern). I measured the length of the sole of the felted slippers (10”) and purchased 10” suede soles. I wish I had purchased 10.5” instead; the slippers needed a bit more room…
