Well, my new bathroom is nearly finished, and my home projects budget is near 0! So I am just starting to build again. We went a bit over estimate, related to problems “behind the walls” that we could not anticipate - fortunately, I had a lot of good advice to have “extra” money on hand for just such problems.
I don’t have a specific thing I’m saving for at this point, but I loved the idea of keeping a home projects envelope. I’m planning to add $500 to that monthly for the rest of the challenge so that I have a start on whatever home project emergency pops up next.
