KK,
I had a week to get a quilt done for a raffle for a cancer patient. I found some great cheater fabric at Walmart, that looked like pieced blocks in gorgeous autumn jewel colors with gold gilding and I used it as a two yard piece, with two borders. I made it in one night, got it quilted in a day at the LQS (we can rent time on her HQs), and put the binding on in a day. Very easy, and quick and I got lots of compliments...most not even realizing it was a cheater. Cost me less than $40 to make and $60 to quilt.
The fabric I used was made by Fabric Traditions and Joanns is now carrying some of the line. I saw it last week, some mixed in with the calicos, and some with the Legacy. They have one in a gorgeous China Blue with coordinating fabrics. You would just need two yards of the pattern that looks like it was pieced, and two yards of border print.
NOTE: one thing to check is that if you want fabric that looks pieced, be sure the print is very straight on the grain. If not, the printed blocks won't be straight across and that could be noticible.
There is also a brown/black/gold paisley with gold highlights that would also make a great cheater quilt, and it has coordinates too.
Call your local quilters to see if someone will donate their services for your brother's benefit or charge a reduced cost and have them do an over all pattern. It is quick and easy for them to do so with a fast turn around.
What I find that is important for a quilt in a raffle, is that the quilt be beautiful to look at. Most who will bid on it or buy tickets, are not looking at the work involved and they don't have the appreciation for it as another quilter would. They will see beautiful fabric that will look great in their home.
I'm very sorry to hear of your brother's illness. Never give up hope and help him live a wonderful life full of love and joy.
