Did you know that you can sharpen your seam rippers? I looked on line because my favorite one has become a bit dull. Yes I know Sean rippers aren't very expensive. Anyway on line they recommended using a bead reamer to sharpen the ones that have become dull. I bought my bead dreamer set from Amazon for about $9.00 for the 4 peace set.
I got some bent nosed weeding tweezers with my Cricut and one day I could not find any of my seam rippers (and I regularly use 3 of them in my sewing studio). I grabbed those tweezers to see if I could use them to unpick a short seam. Wouldn't you know it, those things can unpick and rip seams like the best of my seam rippers. Love it when I can find a new use for a notion.
