I finally caved and followed two pins for crafts I convinced myself I would have the time and/or ability to do. One of them involved the creator referring to questions about how to do the project as "ridiculous." As in, she was used to dealing with ridiculous questions since she teaches elementary school. I bought some supplies, but am still afraid of gluing myself to either newspaper or the table. Or both.
But I figured I had to be able to make luminaries since I had both jars and stickers.
The problem with spray paint is finding a flat, even surface that won't be ruined if uncontrolled paint mist gets on it. Most flat, even surfaces are either things you don't want to get paint on or in areas--like rooms--that you don't want to risk getting paint mist on. Other than the hideous sun slowly roasting us all, the outdoors' other great disadvantage is a lack of flat surfaces. Good things would be not worrying about suffocating on paint fumes.
Maybe some people are able to evenly spray paint things and not have them eventually tip over onto newspaper, but I lack that skill. And while it's probably not entirely Pinterest's fault that the 804 faced Zeus' wrath twice in one week, severe thunderstorms are not conducive to spray painting shit.
These will probably get finished once going outside stops being like walking into an oven. Or I'll put some flowers in them, take a tasteful picture, and put them on Pinterest to torment others.
