what fabric are you using for your seam strips? I can't for the life of me figure out how to make something similar looking!
Actually using a small-rib knit from joanns. it doesn't have quite the right sheen to it (a cotton, vs synthetic on the rest) so i'm tempted to spray over with a clear... something. but seems to be working well so far.
Please don't laugh too much... but... How do you feed the fabric in your machine with the pins and not have a jam.
Just sew slowly and pull the pins out right before you get to them. It's time consuming, but effective....it does make me hate pinning though.
