Prym Aqua Glue Marker - Fabric Glue Pen is suitable for temporarily sticking trimmings, lace and zippers in place before sewing them together. This glue pen is great for English Paper Piecing. Fabric pieces can also easily be stuck together and sewn using your sewing machine without folding or rucking. The glue stick is coloured yellow making it easy to see where you have put the glue. This colour disappears when dry and once washed leaves no traces of glue behind.
