My goodness we're a hot mess! I've just started getting migraines, myself and had a back injury years ago. Just over a year ago I was in a auto collision that left me with some whiplash that took a year to mostly heal and is still hanging on a smidgen. There have been times in the last year when crafting has been the last thing I should be doing for my neck (at least the kinds I do), but w/o TV what the heck else am I supposed to do? Ok, ok I did some reading, but that hurt, too.
I don't think interiors are vital to a Tiny House. Mine has them because of the aforementioned epiphany and engineering. Also, they are probably not what most people are thinking they are. Bwa ha ha ha!
I think that mine will not look nearly as elaborate as all the time I'm taking with it. Admittedly, much of that time is sifting through _____ and _____ to find what I want and then doing it again when I change my mind, ruin one or find the selection won't work. Plus, I'm doing most if it while watching DVDs, so am not fullyu focused (which proabably contributes to ruining selections - ahem). Also, I had some "engineering" to do with mine (that morning-in-bed epiphany I had) so that required thinking and fussing and worrying over.
I've only done a few swaps, but I have to say that my "mediums" take at least twice as long as the definition. I don't think of myself as a slow crafter and my in-person friends don't either, but apparently I am. I don't know if there's anything I make that can be done in the time of a "small" item.
