You know, the things that you have a quick look at when you really ought to be doing something more boring on the computer?
My current favourite is Never Too Small which is mostly studio apartments presented by the architect/designer who created them. I'm particularly impressed by the ones that have a built in cabinet thingy with all the utility of a Swiss army knife. Now it's a bed, now it's a desk, now it's a fully fitted kitchen, here's a hidden TV, everything folds out and then folds back when you've finished using it.
I sometimes watch Living Big in a Tiny House, but am a bit put off by all the loft bedrooms with about a metre of head height above the bed. Every time I see one of those I think I would rather move out than go through the faff of changing the sheets on that bed.
Also a few quilting channels, Jordan Fabrics and Missouri Star, but they tend to be a bit longer, 20 mins or so.
