I haven't made one yet but thought I'd do a quick search for tips for you...
It looks like the biggest is picking the right material for it (good amount of background between prints) and to not wash the fabric before you cut. You want the sizing in it. It kills me to not prewash material before quilting but that's what they say to do for this one - I'll trust it.
I'm planning to make one but sadly it will have to wait awhile. I have a lot to get done before I can quilt for *fun* lol. (xmas presents & dresser scarves)
Oh - I did find a link to this search page which is really massive. You might find some good advice in there as well.
