Here's another vote for urbanelementz.com. They have hundreds of patterns to choose from and their paper is nice quality. You can also buy the digital format if your quilter is computerized. I just placed an order last week and it arrived in three days.
They just had a semi-annual 25% off sale. If you order from them I would order a couple to get you started, then watch for them to have another sale and order several at once. That's what I did.
