1. That different things take longer to dry than others. When some things are dry at the end, I can't get to them because there are wet things that are in the middle. The easy solution would be to figure out what takes longer and put it on accordingly, but that's really a "good on paper" idea and not super applicable to the way I do things - like I'd ever do that consistently!
2. There's this claw-thing with two wheels that's supposed to keep the line closer together, but it just ends up cramping my drying style as it hits the metal attachy-thingy and then I can't put anything else on.
3. I can't get the clothes to not show the clip marks from the clothespins.
I must say - this is a little more complicated than I had thought it would be, but the payoff is worth it. Sheets and towels that smell like nature and a lower electric bill. Woot Woot!
