I think I sewed all the long seams with decorative stitches to hold it all together before I did any FMQ.
You know, I don't think I even knew to pin the layers together with safety pins at that point - I think I straight-pinned along each seam just before I sewed.
I did use an even feed foot at that stage and those things really work.
Go ahead and give it a shot - I love the puffy look on childrens' quilts! If I'd have known it was possible, I'd have probably tried to double the batt in this one, too.
I made one for her brother right after this one, but by that time, I'd gotten tired of banging my head against brick walls and had done enough research to know that flannel isn't the greatest thing for a newbie to start with, much less high loft poly and FMQ on a slant-needle machine. I had also learned about safety pinning and tagging guns. :lol:
