I got a nice table desk (okay, I admit I bought 4 of them) at second hand stores. They are ridiculously sturdy and two of them have a pencil drawer in the front which I find super handy
For some reason, I'm not able to post pics or else I would.
I have 3 of them set up in my craft room, side by side so I have a wall of tables more or less... the 4th one woudln't fit in my new craft room - I had gotten it to raise up for a cutting table but it was really wobbly when we raised it up and it was too heavy for me to comfortably use bed risers. I heard too many horror stories of those giving way and the legs going through them... so I bought a pair of Ikea Vika Artur trestle legs and a matching table top for my cutting table. It's height adjustable which is super sweet. That might be a good way for you to go as well.. so if you are cutting a lot, you can raise it up and when you are ready to sew, you can lower it down....
