Yep, that's what I have ... hinged flexible blades. The hinged blades sure seem small. I could probably get 9 holes in each one if I used a needle (and was very careful). If I go with a 1mm size, I'll probably only be able to get 4 or 5 holes in each one. I might alternate blades and do a combination of both sizes of holes. I'm wondering if a sewing needle sized hole would even do anything ... perhaps it's too small.
