Thanks for all the responses!
Still trying to brainstorm about what works for me. I think that maybe one afternoon a week I could designate "mommy crafty time" and maybe work it out with dh to claim the desktop 1-2 times a week. I just feel bad b/c he doesn't watch TV at all (unless it's sports) so if I'm on the desktop I feel like I'm depriving him. But he DOES have a laptop!
I have no rhyme or reason to my scrapping, I'm so impressed that some of you do. I need to look into this project life thing or figure out what my scrapping goals are, generally speaking!
