Peeverly, that is an interensting question! I have never thought about that, but like TracyLH thought it was something clogging my tip or the consistency of the icing that caused the curling.
I just googled this, and found this text on the global sugarart page under the description of the 0-tip.
"This professional decorating tip by PME is stainless steel, will not rust and has no seam. Being seamless insures no "curling" of your stringwork. For beautiful stringwork, PME's tips are the best. Round opening."
So, I guess that's the point of the seamless tip!
