I do decorative stitches on baby quilts or quilts for children. As long as you don't use a satin stitch type stitch you won't have any problems. When I got my new Janome I did a sampler of stitches I'd like to use for quilts. It does take a little longer, but if you are not perfertly straight it's hard to see the mistakes. I like to use verigated thread too.
