The Fiskars Scallop Sentiment is a plain scallop. I use that one and Fiskars Threading Water a lot. (Threading Water is the same as Scallop Sentiment - same size and shape - but with an added decorative dot). I also really like the MS Scallop Dot. I love scallop punches.
I've tried the tracing thing with a template and for me, cutting it out was hard work. A punch is a lot easier, though borders are tricky unless you have an around-the-page punch.
