Great topic!
I'm not super picky about notions but I agree with using glass head pins.
The plastic headed ones aren't always as sharp.
Also, I bought some safety pins recently from my favorite quilt shop, they were so dull I'm not even going to bother with them. :/ The curved ones always work out well for me, they're just all sitting in another quilt right now. It's marinating in the closet. You know how it is.
And 'pin heaven,' I am still laughing about that!!!
