1.) Have a piece of fabric (I think a similar colored fabric is more helpful than natural or white muslin to see what the stitch and thread color choice will look like) and stabilizer to try out your stitches on first on. Don't forget to try out some of the alphabet stitches, they can be interesting also.
2.) You may need to adjust your top tension down to a lower number to get a prettier stitch. This is one of those times when you want your top thread to come to the backside of the fabric. Test each stitch first.
3.) If your machine has a "Combi mode or Memory" create some stitch combinations.
4.) If your machine will allow you to change stitch width, stitch length or elongate the stitch, play with those features on your machine to change how your stitch looks.
I can't wait to start again on these blocks using this technique.
