Cut socks into four pieces. Try and keep the lines as straight as possible with a ruler.
You can throw away the heel and toe. Keep the section that is in between the two because that will be your cuff for the leg warmers.
Next step, Take the section that will be your cuff and flip one side of it in. One side will look like a cuff and the other side will look like 4 raw cute edges. Make sure that the cuff is not inside out... you should see the print on the exterior.
You are then going to put the leg itself INSIDE the cuff, with the rounded edged facing the top of the sock. You sh ould then have 6 raw cut edged on the bottom like in the picture below.
Set your sewing machine dial to a zig zag stitch (This allows for the cuff to stretch and go back to it's original shape. When you sew the cuff to the legging part, their should be 3 edges you are sewing together. Because of the knit material, the edges tend to roll so make sure you do not miss any edges. Take your time and sew all the way around the cuff.
Check your stitch and trim the extra being very careful not to cut your stitch
And your done! These would be so cute on newborns all the way up to big girls. They are great if your little one likes to run around in nothing but a onsie or to put under a cute little dress or skirt. They can wear them up to their knees or pulled all the way up to their chubby thighs like shown in my pictures below.
If you have any questions, feel free to comment and if you make these, send me a pic! I'd love to see them on your little one!
