If I'm painting a mural I'd much rather do the focal parts first -- like the animals or the people, then I lose interest when all that is left is the background scenery. When I'm sewing baby quilts (I don't do anything bigger because it takes too long and I get bored with the pattern), I love to design and piece the top, but the quilting gets tedious really fast.
The problem comes when I'm trying to get from one dot to another. The hoursI spend and the anquish I endure on the tedious transitions from one big scene to the next. I mean, it has to be there, but... UGH!
