I made a pair each for my 2 and 4 year olds. As Jessi mentions in her tutorial it was tricky to sew the curves, particularly around the heel as the kids socks are so small! I used fleecy fabric and sewed on my serger which is trickier still for curves (well I am a newbie to serging) but I used a flatlock on the serger which I think gives a lovely finish and no seam bulk which I really didn’t want for those little feet.
I embroidered the top to make the socks totally original and remove the need for name tags for school. I was pretty pleased with the result.
