Dritz Brand Fray Check Liquid Seam Sealant
$4.30Fray Check prevents fabric from fraying. You simply run a small bead of it along all of the cut edges (of your doll-clothes pieces) and it (mostly) disappears when dry. I use it on all my quilting cotton and muslin coll clothes because I don't like the look of double-folded hems (too bulky). Use Fray Check and turn single folds into lovely, clean hems.
