I keep a small notebook by my machine too, started years ago when I began to do applique - needed to remember those stitch lengths as you said:) I've moved on to also keeping track of projects that are on-going, name of pattern, finished size, even designer & mfg' name/sku# of my fabrics. It gives me a sense of accomplishment when I can scratch off a project---& even better when I need more fabric & know exactly what I'm looking for!!
Isn't the board a wonderful place to share tips & ideas??!!
