I seem to have lots of friends having babies or grandbabies, so I make a lot of baby quilts (usually 40 x 40 or so). I've also made a few lap quilts, about 60 x 72. I don't have a lot of room for the quilting part, so haven't tried any very large ones. I'm going to make my neice a quilt for graduation, probably a large twin, for her dorm room. That will be my biggest effort. I'd love to make a king for my bed, but I'd have to do a quilt as you go or have it quilted by a pro.
