You're best to ask the powers that be!
I entered in a show this fall, the class was "a quilt with at least two different techniques". I had one with a little applique and was tempted to sew some beads on to get my 2nd technique. Read closer, and it said, eg. piecing, applique (and gave some more). ummmmmm ... piecing, a technique? I would never have entered that class, but the sub comments said so.
There was another class that again, I wouldn't enter normally just from reading the info. I spoke to the contact and asked questions ...... suddenly, I was entering more classes!
So speak up, and check what they mean ..... rather than entering and being disqualified, or being disappointed when you discover the winning quilt is a mate to yours!!
Good Luck! And enjoy the glory of seeing your quilt in the show!!
