I find I like scrap quilts, more different fabrics & colors in them, the better! I also like doing sampler type blocks, so not every block is the same, over & over... I seldom start & finish a quilt, without working on others too. Works for some I guess, but not me, lol... Having numerous ones going help too. I like handwork, I can do wherever, then ones I do at my machine, & sometimes, I want easy, other times, I am looking for a challenge, so more than one going is definitely good! Find what works for you & makes you happy, & go for it!
