I'm attending Teacher Certification at Quilt in a Day - they only had a limited number of machines to use, and I'd feel better using a machine I'm very familiar with (more time to concentrate on assignments, less time fidgeting with the machine.) Their machines are Babylocks, and I have Vikings and Brothers - figures! I'll be there 3 days, so it'll be worth the trouble (not to mention leaving all this Iowa snow for Southern California!)
