I've found that a 'filler' type design is easier for me to do than the meanders. I would much rather quilt the little clamshells (paisley) than stipple! For me it's how far you have to move the fabric. Big long lines or arcs are more difficult to do on a little domestic machine. Plus they need to flow a lot so there isn't a very natural stopping point. Here's leah Day's link to the Paisley:
