I have two tables I purchased at Staples. One is six foot and the other 4. My husband was kind enough to cut the legs down on the 4 foot one to make it only 28" high. That allows me to use my slide on clear extension table with my Bernina Artista 185 perfectly. The space under the clear extension table is great for storing my accesories like bobbins and feet etc. They are totally visible but out of the way. The 18 inches to the right of the machine allow plenty of space for my pin cushion, and other useful notions as well as a small three drawer plastic storage unit that holds thread etc. etc.
Underneath the table to the right side is a larger plastic drawer unit that holds additional thread and sewing tools that come in handy. I made a skirt to hide the stuff under the table by attaching stick on velcro on the back and right side of the table and attaching a curtin that hides all the stuff from anyone walking into the room. I also purchased a swivel office chair from Staples and use it when sewing. Behind my sewing machine set up I have another table from Staples. This one is six feet and holds both of my stand alone embroidery machines. Underneath are three more of the plastic storage units filled with various accessories for the embroidery machines like hoops, stablilizers and thread of course. I can access those two machines from my same rolling chair just by turning around. In the space inbetween I have a small side table that holds my Serger. All of this fits into a space 8 1/2 ft by 6 1/2 ft. I probably have less than $300 tied up in all of that. My main cutting surface is downstairs in my basement stash room. I use a former bedroom dresser for a cutting and ironing surface. The drawers underneath make great storage. I have also made use of the vertical storage space above the cutting area and the table holding the embroidery machines by hanging open shelves that hold a lot of sewing and quilting related supplies. Once I figure out how to post a photo and have the area cleaned up I will try and post some pictures.
