I always swap in between quilts, works well for me. I get bored but then I don't have deadlines so I'm not bothered by time. I would do the one your most excited about first and go from there. For example were doing a birthday quilt for our guild I was getting bored with it til I saw a cupcake pantograph now I'm ready to finish it so I can quilt it. I'm intimidated by my bear claw quilt so I only have 2 of the 20 blocks done, it's for our bed so I think I'll get really motivated when the cold hits!! Get excited and you'll find your inspiration!!
