I love scrappy quilts.
My assistant two greatgranddaughters will chose the fabric from my scrap bin that will be sewn together. Then they take turns deciding which of the pieces get added next. I would have never put some of those fabrics next to each other. I have received a lot of compliments on the ones that the girls help with.
Do not worry about how to colors look together. Wait until it is finished and then look.
One thing about scrappy that I have found works well is to add a color for the eyes to rest on. This will pull the scrappy together.
