Hamanaka Felt Preforated Slipper Soles

Wow, I got something that will help making slippers so much easier. They already come with holes and look so comfy. They come in a pair and are about 1/4 inch thick. I love them. I will try one myself and make a great pair of house slippers using the Croching for warmth series book. I'm so excited. :) They are one size only. I think it's one size fits all but I'll have to test it out myself to know for sure. The length of the sole is 23cm or 9.2 inches. Let me know if you have any questions.
