That Purple Thang
I use this crazy little Purple Thang to open up my seams. I get the seam to start to open with it, then I use my iron. Saves my fingers from being near the heat.
It pushes, pokes, pulls, fudges, stuffs. Every quilter, crafter, seamstress needs one. You can thread a ribbon through the slot and wear it around your neck. Made of heavy plastic.
