I bought a wooden dining room table at a yard sale for $20. My hubby cut the legs down to the right height for me, then cut a hole in the table, built a drop down shelf where the machine sits and TADA I have a nice big sewing machine /work table!
Also, if you look in the Keepsake Quilting catalog, you can buy plans for a nice cabinet for only $15 and its fantastic!
Good luck~!
