I just finished a 110" x 110" king sized one on my Bernina. After reading thru the other posts, it seems that most 'bunch and pool' rather than roll. I have found 'bunch and pool' to much easier too. I always put my ironing board in front of my machine table to catch the bulk of the quilt from pulling and have tables on my left to support the weight. Some type of gloves help with the movement. I have machingers or I use surgical gloves - they really let you feel your quilt. I spray baste, but also use safety pins, since I am doing so much bunching. I've stippled, SID, quilted each block, cross hatched, borders... my life doesn't allow long periods at a sewing machine, but then if I can get an hour in here and there, then the breaks(work, meals, sleep, etc) are forced, and eventually it gets done! I have always been pleased with the results, and that is good, because I don't have room in my house for a long arm!
