I’d stick with my husband’s sewing machine table he made for you and forget this cabinet. :-) I think you will be happier without it. Also if you need more storage for items, get a cabinet that will fit in your space. It will be a better use of $$$.
I also think you will not be happy if you cut down on your available flat spaces...just saying....I have a 5’ ironing table and a 6’ cutting table, an “in the cabinet” sewing machine cabinet, plus another table set up with a sewing machine and I still don’t have enough room to lay out my project. :-). :-)
