hello! rather new here, but I just wanted to ask 
some questions regarding fancel making:
1) what type of acetate do you recommend to 
use...I have some acetate lying around here 
(bought from local bookstore) but I have no idea 
what type they are..if they'll warp, etc... I 
heard that 5mm acetate is good for fancel making 
(how can you tell if its 5mm?)
2) what type of pens do you use? I'm using 
staedler lumocolor..and so far I've had bleeding, 
ink running out (then flowing again) problems 
with it. Any suggestions?
Thanks!
