The sewing table my DH is making for me will be 30" high. I have the Janome 7700 as well and he built a depression area for it to sit in so the extension table and machine will be table height. Right now I have to sit on a pillow to get me to the correct position to sew when my machine is sitting on top of a table. Not a great way to sew--bad on the back and shoulders. My cutting table is 36" high and is absolutely perfect for cutting. I am 5'6" tall. No more back ache when I'm cutting!
