Looks great! I have a sewing table I bought from a yard sale, a desk gotten at a second hand shop, and a folding table from Walmart that I combined similar to yours. It did shrink my space some but love the set up.
An expensive sewing station is completely out of the budget due to health issues. When I think about it, I'm not sure I would be any more pleased with an expensive sewing desk and cabinets than I am with what I came up with. For under $100. I have seen the suspended system and wondered about that but for now my station works.
