Some months ago, my favorite sock site started selling these super cute, knit leg warmers then buttoned up the side. Unfortunately I didn't have the money they wanted in exchange for them, so I set out to make my own!
And off the to thrift store I went! I managed to find a brand-new big, thick men's sweater for the leg warmers, and I purchased the ugliest, frumpiest dress that ever existed so I could reuse the cool buttons it had down the front (oddly enough I still have the fabric, you know... 'just in case'...)
From the sweater, I cut off the arms and neckline, and down the sides, to get two large pieces to make the leg warmers out of. I zig-zag stitched as close as I could to the edges, though I really should have learned to use my serger and done that.
I did try to actually make button holes, but my machine was having none of that! So I folded one edge over to the size I needed and sewed it down, then attached the buttons down the side.
Pretty easy overall. I need to go back and fold the top edge over since these are a little long on me and don't stay up well. They are really quite cute though!
