YAY , Fred! Thank you ! This is what I needed... I knew the decal
would stretch and knew I d have to cut it ... and it will work even
if I do thin plastic templates ... Just needed to confirm that I was
thinking correctly on the measurements thing ( transferring the
measurements from the 3D piece to a flat paper ) . Math was never my thing .
And thank you again to everyone who responded. I appreciate it
very much . You guys are the best !
Clayart ROCKS !!
