Butterfli - that sounds like a wonderful project! I hope your JoAnns has more fabric than mine does so you can get everything you are hoping for. With regards to quilting it, after you've done the exterior edges, you can always do a running stitch up and down the quilt to make sure that all the batting is secured as LAF said. He is going to love it!
Snooze they are lovely! What a great idea to use fruit and vegetables as your blocks for your farmer friend.
So creative!
