I know lots of LAers have HUGE backlogs....
BUT that does seem excessive. Since they are friends, if *I* were your friend, I would ask for a date for when the LAer was going to be able to get them done. If it's still too far out, I would ask for my tops back so that I could get them done. Obviously, the LAer friend doesn't need the business, but your friend needs her quilts finished.
Done nicely, your friend will have her quilts done one way or another and they can still be friends.
Scheduling of quilts and how to handle our backlogs has been subject of discussion on the LA sites. It's not always as easy as you'd think. 10 baby quilts with all-over designs is not the same as 10 king size quilts with different designs in each block, plus the sashings and the borders (also known as 'Custom Quilting').
Here's how I handle my backlog: When a customer wants to schedule a quilt, I let them know when my first opening is. They can choose that month or beyond. I don't want the quilt into the studio until about two weeks before the beginning of that month. If I happened to have 10 baby quilts in February and get done early, I will start in on the March quilts early, so that if one or two of the March quilts are Custom I will still have plenty of time to get everyone finished. The order of the monthly quilting is determined on when the quilts arrive in my studio.
