It has been lots of fun for me to follow this chat! I’ve done a fair amount of machine quilting which is really very much like what you are describing. Those who are trying it for the first time may want to consider using a cotton fabric, batting and a muslin backing. Insert all three layers in the fashion described and GO! When I am meandering around on a quilt I think of puzzle pieces and try to follow that type of mental pattern without crossing over any sewing lines. Large cursive “l” or “e” patterns are fun too. Another idea is to cut out a simple shape and then go round and round that shape with each line of stitiching being about 1/4 inch apart. (Echo quilting).
I loved your idea of trying a web or initials! Does anyone know anything about “thread painting”? I would like to know more about that……or perhaps I’m mistaken and that is more of what you were referring to?
