The one on the left is recommended for baby things, but at least in this thread it looks kind of skimpy to me. I like the other one. It is a four step stitch. You can do just the shell type stitch alone (619) and I plan to try that one and a few others. Right now it is back to my sewing room organizing/cleaning (groan)... I have played enough for now! There are books for all of the major machines and she gives stitch numbers, tension, length and width. You use heavy WSS underneath the stitches and extending out past the stitching. I was practicing on scraps so next time around I will go with a bit heavier, and a bit wider.
Why green? You need to use a heavier thread... and I happened to have this Sulky 30 wt. cotton, and I already had a bobbin too... you need to match the bobbin thread exactly... must say the ones I have tried do look good from both sides!
