Peg, the fabrics look lovely, but I'm concerned you may not have enough contrast if you use them as shown. They sort of look like all the same tone - some a little brighter and some a little darker.
I would recommend making one or two sample squares and taping them on the wall, then step back to the other side of the room and look at them before you do too much cutting - with whatever pattern you choose.
Let us know the quantities of fabric and the size of the quilt you want to make so we can help you out.
