To whip this project up we have a cutter:
2 baby tenders:
My feather weight worked like a charm!!! . . . non-optional snacks close by.
. . . second seamstress on the pfaff.
and a delivery boy.
For my personal future reference:
50 sashes, took 3 hours with 4 sewing helpers. Make sashes 12 inches by 2 feet for just a tie and a foot or 2 longer if you want to tie it in a bow. Tear lengthwise, sew the ends.
