I kept quilting, hoping it was okay, but I did double check yesterday by hanging the quilt up, standing back from it, and taking a photo. I can still read "america" clearly and this is after the quilting has gone above the letters:
In fact the perle cotton is almost too much. Keep telling myself I like this much emphasis on the quilting. I use embroidery needles size 10 to quilt with perle cotton thread - more details can be found here. The white stars measure 1.25" across.
By the way, I am using a flexi-curve to mark the lines for quilting. [Thanks, Jan, for reminding me I own this tool.] I want undulating lines to make the quilt look like it is blowing in a gentle breeze. When I've tried quilting this pattern freehand my lines just keep getting flatter and flatter and flatter. So yes, I "cheat" and mark them. Not making them exactly the same and I'm using thick chalk to mark with, so they still look freehand.
Pokey, taking advantage of me putting the quilt down for marking:
Pokey has decided the flexi-curve is a toy and keeps attacking it. And Bibi has become fascinated with the quilting thread and want to sit on my lap and paw at it. Silly cats.
