I'm with Bob on bath towels, we change them after two uses. same with washcloths, so it takes about a week to accumulate a load of towels since I change kitchen towels/rags every two days as well.
Sheets get changed once a week, but we have thin smooth-textured sheets. Since we are both hot sleepers, we don't care for thicker flannel type bedding or anything like that. Consequently, three sets of full-size bedding and pillowcases can be washed together easily with a bit of room to spare. Therefore, I do a load of sheets every three weeks.
We only do blankets about once per season, so approx. four times a year. We use a top sheet, so blankets don't get very dirty and we both usually end up throwing them off in the middle of the night anyway.
I tend to follow the same rule for pillows as blankets. I wash our pillows about once per season on the bulky cycle. I feel like a good wash and a hot spin in the dryer kind of re-fluffs them. We've had the same pillows for ages and they still are thick and puffy like new.
Don't have throw-rugs or anything like that. We have carpet in the bedroom and laminate flooring in the main area of the apartment, and rugs tend to bunch up under Stacye's wheelchair, causing her to get stuck, so we avoid rugs.
Jeans/pants get worn twice, sometimes three times if I only had them on for some of the day, like if I changed into lounge pants upon returning home from an outing which I don't often do. Stacye won't wear pants more than once because she alleges sitting in a sweaty wheelchair all day makes her feel self-consciously smelly in the pants region. I've tried telling her this isn't so at all, and that wearing pants more than once won't hurt a thing, but it's a hard line, so I let it go long ago. Some battles just aren't worth fighting. LOL
