gorgeous! I would love to know how you made them
Trial an error.....lol, and a bit of cursing. I basically measured my friends baby foot. He wasn't all that willing considering it was for girls shoes...lol. I drew a foot shape, kinda like a jelly bean, with an indent for the instep. Then I took a piece of string and followed the shape all the way around then measured it on a ruler. It's hard to measure a round shape with a ruler alone, so the string works best for me. This measurement gives you the distance for the top of the foot. Then I just played with the shape on paper. I would say this size is a 6-9 months. I am sure you could google baby booties and find some free patterns too. I just like to create from scratch. I am working on a boot style too, so we shall see how that goes.
Thanks for the nice comments!
