Sounds like a labour of love. All the right ingredients there: recycling, made to measure, determination to see the job through. I bet they last for years.I built crates from pallets. Using a Facebook group for people who give away things, I was able to obtain pallets for free, broke them up into their planks and built three sizes of crates: a type for 75cl bottles, a type for 37,5cl/long 33cl bottles, and a type for Duvel type 33 cl bottles. Took me an autumn, spending an hour every evening after work building them.
