(He only comes into my sewing room on an invited basis, usually for me to either show something off or solicit his help with choosing colors for the next project, so he really has no idea when my fabric collection grows, and since it still fits (for now) in a closet, how would he know the difference anyway?)
My DH is color insensitive. He can't even sort clothes for washing. He will help with everything else with laundry but not the sorting. When my oldest was 10, I had to go to California for a few weeks to visit my father who was terminally ill. I left my son in charge of laundry and cooking! Otherwise they would have been wearing pink clothes and eating McDonalds' for the entire time.
But, my DH provides me with plenty of FART's and SEX! Whenever he plans a road trip, he includes stops at quilt stores even if it involves a detour. Just last month he took me to Missouri Star Quilting Company! He even pretends to believe me when I tell him I'm all out of fabric and need to buy more.
