It's a top!
63 x 77
It started in January as an Ad Hoc Improv Challenge to make a Chinese Coin quilt.
I knew immediately I was going to make a rainbow, use bits and pieces from the "parts department" and make it approximately 60 x 80 and when finished it would go into a pile for donation to someone who needed some rainbow cheer.
I first gathered together bits and pieces I had laying around here in one color. That included some four patches, crumb blocks, miscellaneous four inch blocks, postage stamp blocks, leftover rail fence type pieces, ends of 2.5 inch scraps I had sewn together into strips. I made some stars out of crumb blocks to get bigger blocks and I made some red flying geese but other than that I basically just had to sew a few four patches, postage stamp and crumb blocks together into strips measuring 20.5 inches.
Rows and columns are separated by 1.5 inch blue (sky behind the rainbow) strips.
When the three columns were all sewn together I had an almost squarish quilt at 63 inches in width and 65 inches in length. That was a little off my goal of 80 inches in length so I raided my chunks milk crate for some 6.5 inch pieces in rainbow colors and made some six inch HSTs for the top and bottom - arranging HSTs in rainbow order. I think I intended the color side of the HST to be next to the main body of the quilt with the blue on the outside but sewed them all together in reverse order so that's how it goes.
