Yes and no. I have a full set of all the cheapo Amazon sizes. 3mm, 4mm, & 5mm.
I have one set of Wuta pricking irons in 3.85.
I also have the crafttool pro 2.7?mm pricking irons, which I find totally useless.
I am finally getting the zig zag. And it is completely simple.
At least in my head.
Here goes.
1. Pick the front.
2. Front needle always goes on the bottom to the hole.
3. Back needle always goes on top of the hole.
4. Rinse & Repeat.
5. The back is the back, let it be.
That's how it's working for me, anyway.
