It is very easy and quickly to make such moccasins and they look so adorable! Perfect for both - girl or boy!
ALL MY PATTERNS ARE WRITTEN IN STANDARD AMERICAN TERMS!
For your convenience there are step by step description and many photos.

Pattern is made for one size but you can change the size of booties just by using different kind of yarn. I suggest to work with DK-weight yarn for size 0-6 months and worsted-weight for size 6-12 months.
