I have been fighting with my spool of Zing-It for MONTHS trying to splice it. I followed all the tips I read here, and never had any luck. Well today that all changed;
For anybody who still has difficulty splicing zing-it/lash-it try this:
Use a (large) paperclip & needlenose pliers!
Unroll the paperclip so it is long and straight. Fold it in half, and use the pliers to pinch it tightly together. (Very important step)
After you create this tool, follow all the other how-tos, and you too will be splicing that crazy small stuff.
So between using a paperclip & pinching it tightly together, I think I found a winning formula that works for me.
My wife is getting annoyed at all the things I putting loops on around the house.
