Congratulations! Wow, how exciting! I think getting your room to fit YOU and make you feel comfortable when using it, like getting the right height for your cutting table/ironing station. Storage under it. I love scrappy quilts, so having a scrap storage system would be great. Do you have a huge stash? built-ins for folded stash fabric with glass doors to keep the dust out. bookcases for books. how many machines do you use? I have 3 that I use all the time, having them in a table/counter flush so quilting is easier, LOTS of plugs and LOTS of lighting. I am a collector of Unfinished projects, so having a file/drawer for just projects to be done later, nice. Design wall? Wood floors so chair can roll across. Of course an area where you can sit and read the quilting board.
