Who makes some really heavy duty safety pins? I've done a number of searches looking for some tough ones that are also resistant to rusting, but i can't find anything definitive. The ones I've been carrying are junk. After a popped a button on a pair of pants the other day and tried to do a quick fix with a safety pin, the things just kept bending up instead of going through the canvas pants. I also noticed they had a few spots of rust on them after only a year or so in my bag. I just ordered a few of [ftphttp://www.spiraleyeneedles.com/][/ftp]. They look pretty cool and easy. Just trying to make a really useful sewing kit.
