Do you (or someone you know) do a lot of craft projects? This craft table with pigeon holes will let you keep everything tidy, organised and close at hand. http://theownerbuildernetwork.co/bm4h It’s easy to build and modify to fit your own room as it is basically three shelves connected by the table top frames.
Nice Idea for sewing desk. Make the table Counter height and possibly a bit wider. Use the extra shelf space gained from the additional height to store the sewing machine when not in use. If possible make dimensions so that the shelf base can be turned either way depending on situation of table.
