I am in a hand quilting group that has seen a few creative licencing going around over the years.... A large open safety pin somehow was caught between the layers and quilted in. Thankfully there wasn't a lot of quilting that needed to be taken out, just a lot of fussing.
Then one of our members brought a woman with her for a few months to learn how to hand quilt (she never really did...no knack for it at all!). She'd been coming a few weeks when one of the ladies came up missing her favorite scissors. Now we'd been together for over 20 years so she trusted the rest of US, but no one really knew the new gal, right? Oh well, what can you say?
Weeks went by, and one day I stayed later than they to get a tricky bit finished. When I rolled up the quilt to place in the closet I felt........those scissors, in between the layers! Had to take out quite a bit of quilting to liberate them this time!
