I am working on a slipcover that needs a couple of skinny ties, so I got out my bias tape maker, and thought I would do a demonstration, for anyone who hasn't used one.
They come in different sizes and this one makes bias tape (or a tie) that is 1/4 inch wide. Start by cutting a one inch strip on the bias if you are making bias tape. I didn't cut mine on the bias because I am just making straight ties.
Feed the strip into the wide side, using a pin to pull it out the other side.
Press the now folded strip as it comes through the tool.
You now have a "tape" that is 1/2 inch flat, or 1/4 inch folded.
To make my ties, I just stitch the open side closed near the edge.
I back stitch the end and apply Fray Check to keep it from raveling.
You can order them here or at just about any place that sells sewing notions.
