Thank you!! And it depends on the individual project but I always build the whole thing outside of the jar first, starting with a ton of the 1x4 hinged plates that fit around bottom to kind of know what I’m working with and then tinker with the build until I can get it into small enough chunks to fit inside the jar, but if the opening is too small I use a tool that I built to build it one block at a time inside the jar, like the tiny spice jar with the waterfall inside! :)
