Seriously? Guy has a long straight edge, uses 30cm ruler to cut. Wets entire piece for 1 small stamp. So much wasted time here. Get a 1T arbour press for your stamp. Will take 30 seconds. I make a 400mm x 750mm desk mat with an actual hand stitched border in about an hour, and I dont sew that fast. Ditch that horrible sewing machine. The thread tension is all over the place.
