I don't like to think things, I like to know things. So when I first saw quilts with pieced backs, which my mother never did, I thought "Well, why doesn't anyone make both sides the front. I will be the FIRST EVER to do this."
Actually... I get into trouble a lot with this sort of thinking. Like when I decide it'll be easier to sew a seam before turning the purse inside out instead of after like the instructions say... and then discover that with the seam sewn it is impossible to turn the purse inside out.
In case there are other curious souls out there who couldn't figure it out without trying to do it...
a) lots of work
b) more piecing on front and back makes it harder to quilt evenly
c) impossible to get both "fronts" lined up perfectly, so one of them will be a bit crooked.
d) only one side can point up, so why waste all that effort?
If you decide you want to do this, I recommend extra size borders on each side so that when you trim the crookedness won't be as noticeable.
So here is what I made, in red for my second-to-youngest niece, who has a fresh and bold personality even at the tender young age of 13 months.
The front of the quilt is similar to the green version. Here it is before quilting:
The other front is a nine-patch using the same red:
And for my second foray into quilting, I closely quilted the blocks on the front in a spiral pattern, leaving the sashing unquilted. I like how it emphasizes the blocks, but it was a pain compared to the diamond quilting on the green version.
fyi, my sister is using it nine-patch side down.
