I am going to a crop in a few weeks (whoo hoo biggrin]

) with some friends and quite a few are bringing their expressions. I was asked to tell about tips and tricks (it was determined I use mine most

)and thought I would do up a little cheat sheet and was looking for the most valuable tips to include.
Of course, my mind went completely blank (not unusual these days

) and I can only think of a few things to include
Extending mat life by rotating/adhesive/cleaning
How to cut again in same location (this applies more to baby bug)
Center Point option
Real dial size vs regular size vs design studio size
thickness/speed vs paper type (i.e. Bazzill vs AC Cardstock, vs DCWV, etc.)
stickiness of mat vs paper types
cutting chipboard
deep cut blade vs regular blade (deep cut works on baby bug, but not my expression, yet)
Someone also mentioned buying 12x12 mats and cutting to fit baby bug - has anyone ever done this? I haven't - mainly because I have a tough time finding 12x12 mats in my area.
Any other good hints I may be forgetting? (ps - if you give a hint and want a copy of the sheet once I have it typed, pm me an email and I will send to you)
THANKS!! for any help
