Ouch!
I'm so sorry you have such an expensive boo-boo to deal with. Hopefully, they'll have it repaired real quick and you can get back to quilting.
I like the fine fabric tagging guns for basting instead of safety pins - they're so flimsy and so tiny that I don't think they would cause even a little bit of trouble for even a delicate mechanism. They're a pain in the neck to remove, but if you do sew over one (which I've done many times!
ops: ) all you have to do is snip the tag along both sides of the stitching and you can remove the tag.
I just sewed the plastic head on a flower pin into a paper-pieced block last night.
I am very grateful that my 1947 Singer could sew through a plank if necessary and not cause herself a trip to the hospital - but boy, I sure hate making a mistake like that.
