Pattern is made for european size 37 (USA - 6,5, UK - 4, Australia - 5), but it is extremely easy to make it in size you need, in pattern I explain how.
These slippers are made with soft angora yarn (40% Angora 30% Nylon 30% Acrylic), but I am sure they will look wonderful with any other angora yarn, 100% wool or 100% cotton.
For your convenience there is step by step description and many photos.
I am always available for questions if you have any problems with your pattern.
