The skirt for my mom is done! I decided to go with the circles, but with a little different layout. I had a pretty hard time getting the pattern pieces for the skirt to fit onto the pieces of linen I had, but eventually I got it to work. I used this method for my circles with varied success. I figured out that the less foil you use, the smoother your circle. But I figured that out after I had finished a couple circles. I think they look ok, and will look fine when my mom's wearing it. I will definitely use this method again, but now I know how to tweak it to make it look a little smoother. Maybe next time I'll use a decorative stitch to attach them instead of a straight stitch.
Now all I have to do it wrap it, and I'm done!
