I may be a bit late to the party but I just wanted to add that I have high quality, non-toxic, nickel plated French barrettes and alligator clips in the 30mm size which is perfect for bow making.
I also sell them at a discount in larger quantities (packages of 10, 20 & 30) - and you can use your YT discount code on top of that for additional savings.
