Something changed in Toronto last spring, in that berries began being sold in plastic baskets rather than the recyclable cardboard ones that we were used to. We ended up with two of them and were confused about whether or not they could be put in the recycling bin, so they ended up sitting in the corner of the counter until I scooped them up and put them with my crafting supplies. (Today, I remain confused about whether these are garbage or recyclabe, as the city's website still doesn't mention them at all, so don't quote me, but I think they likely go in the garbage.)
Here's what I made with them -- By weaving some cotton yarn through them, they were transformed into Springtime/Easter baskets! They weren't particularly quick to make but they were quite fun and didn't require much concentration, so I could work on them in the evenings while we watched Netflix (Season 2 of The OA, to be precise).
Perhaps you have some of these baskets hanging around, or will be bringing some home once berry season kicks in, and would like to try this craft yourself.
