Right... rolled and die-cut is much flatter, but the only (couple)=20 bakeries I've found who can do that wants $4 per cookie, and will=20 *graciously* give me a 10% discount for 300 of them... that's still=20 $1100 is cookies that I'd be giving away. I don't want to make my own,=20 because I have enough going on here, and also since I've already=20 researched/discussed/found out that if the cookies and frosting are=20 pre-made, I don't need a food distribution license. Anyway, at this point, I have much to do on the software due to some=20 lock-ups, so I have found a cop-out, and will drop the whole=20 distance-sensing part for now... I'm printing on the underside of the=20 cookies. I can easily visually tweak the height before each cookie. I=20 just ordered 300 cookies ($75). 4 days left until Maker Faire!!!
