it is difficult to actually get a good price from kid's size quilts; most people are not willing to pay more than $45-65 for a kids' quilt. i used to make game quilts by special order, i could not make one for less than $125...so i hate making them to sell, i just give them away.
your quilt although cute would probably be hard to sell for more than about $50 it is best to save the expensive fabrics for quilts that you can charge more for. you will be lucky to break even. and i know everyone has mentioned this but i'm going to add again...
buttons should not be put on kids quilts.
i have sold literally hundreds of quilts...and anything smaller than a twin i never made any money from; barely break even...or take a loss...larger than twins sold well and i could sell them for $125-$150.
there is a lady that has a booth at a local farmers market...sells quilts for $30 and tote bags/purses for $7.50; no-one around can compete with her. and it does not make a difference that she uses goodwill scraps and $1 a yard panals and the next person pays $10 a yard for their fabric. unless it is a quilter looking regular traffic just thinks you should buy from her, everyone else is over priced...so i avoid that venue...
