I do my RTW quilts in quarters -- I find it is easier to sew the strips if they are shorter. Then I only have the 2 seams for the quarters and 1 long seam to finish it all.
I hand quilt sometimes shadowing the pieces, sometimes diagonal corner to corner.
I do a 6 1/2" square swap betting on baseball teams so I get and send several hundred pieces a year. After I separate into color piles, I can plan a RTW scrappy quilt.
