hey Thank you Von Lucky!!...
Connectamabob,.....First thing i do when i get my big sheet of foamcore is strip the paper off of BOTH sides...that leaves nothing to wrinkle...then just measure and get ready with the glue of your choice...i use elmer's fast dry i find in the craft section of wal-mart(or any craft store)...and some rubber bands ...then glue up the tube you are using and s l o w l y wrap the foamcore...and yes...it can get messy with slipping and moving around, but in the end it's worth all the possible hassles...once you get it wrapped, rubber band it for a few hours(i let it go all night)...and voila...it's ready to be carved.
