I have never seen monofillament thread available here, but I think the gray will blend nicely enough through the rest. I don't mind if it shows up some, I just don't want to do, say, red all over and compete with the comics for attention.
Good tip to keep the density the same all over. I don't think I'll try to FMQ over his designs; I've tried following drawn lines and am just not good at it. I would need a LOT more practice. Well, maybe I could do some; his drawings are of a volcano/mountain, so I could at least do the straight lines, and maybe the grids in the places where I put more than one comic on one sheet.
I hand-quilted something with that clamshell design once; it really makes a beautiful texture. When I hand did it (on a small project) I used a thick, stiff felt thing such as you put on the bottoms of chair legs as my guide and quilted around that; is it possible to maybe tape a guide type thing to my quilt and use it to guide my FMQ foot???
My biggest problem with the FMQ is speed control; my machine doesn't have speed control, so it's all in how I work the foot pedal. I guess practice is the only answer there, for keeping my machine speed and the speed I move the fabric through balanced out so that I get even stitches......I wonder, does it show up less with a smaller stitch length, or longer??? gosh, I have so much to learn.....
so glad I have you guys! (err, gals! ladies! whatever, you know what I mean!!)
