Try LEAH DAY's blog spot for quilting ideas for different filler patterns.
She also has a quilt a long going on for FMQ ... LOVE her stuff
I made a quilt using a lot of her free motion patterns. Each block started at 13 inches then I made half sq tri from them. I did sew the blocks stitch in the ditch to stablize the blocks in the quilt top. Each white back ground tri ended up with a different free motion filler . I was practicing FMQ techniques. I think it helped improve my skills. I love LEAH's YOU tube videos.. they were fun to watch and instructional.
The color blocks looked trupunto and stood out. It was a fun quilt. I had pictures once upon a time but lost them with the computer crash. I plan to take pictures again when I go to visit my niece. ( I had given her the quilt.)
Just remember to have fun with your projects.
