This baby shoe knitting pattern comes in two sizes: 0-3 months (8cm long) and 3-6 months (9-10 cm). It uses a doubleknit wool, and if you chose something with a percentage of mohair or alpaca, they will have a fluffy almost felted look.
I think the simple shape just shows off the loveliness of the wool, so I suggest you pick a wool that you really love.
The shoe is fastened with a button, and this button flap is functional, so you can really easily put the babies feet in.
I have tried to keep the knitting simple. Each shoe is made from just two pieces to knit, and the shaping of the top piece uses short rows to give the elegant curve. For more information, see http://ginxcraft.blogspot.co.uk/2015/04/wrap-over-baby-shoe.html
