I have experimented with both the blackberry stitch and the bobble, against a garter stitch background and a stockinette background, but can't decide which looks better. The idea I had for the dashes - yarn forward, slip 3, yarn back - doesn't look very good - the yarn just hangs loosely. I can't find the washcloth I knit - the pattern you suggested, Salmonmac - to see how they looked in that. It's around somewhere as I saw it recently. I did try using a different colour, but that didn't look very effective either.
Marilyn, the mitts look very pretty, but I don't see any clearly defined morse on them.
CMHoover1, I haven't quite got to the graph paper stage - I think I'll wait until I decide what stitches to use.
Still open to suggestions.
