I saw a circle one used in a shop recently - WOW! I want some! I am new to longarming and am having difficulty with smoothness in my pantograph quilting. I tell my husband that I have the "herky jerkies" - lol. I wish they weren't so expensive - but ... if you spend $500 for a king-size one, and you charge to do a king-size quilt, I imagine it wouldn't take long to pay for one ... or two ... or three.
