Go to Office Max and buy a "personal table" (looks a little like a cocktail table but it has adjustable heights). Next go to Home Depot and buy an 18 x 24" 1/4" thick sheet of clear acrylic. I have made about 6 of these for myself and friends. Here's how: (If you have the tools, its easy to do it yourself and if you don't have the tools, find a friend that has them and here's what to do.....
Counter sink holes for seven wood screws. Drill through the countersinks to accomodate the screws. Cut off 3/4" dowel rod at 3 1/2" lengths. (Cut 7). Purchase seven cheap white plastic tips for the dowel rods. To cut the opening you'llneed for your machine, lay the acrylic over the arm of the machine and mark where to cut with a permanent marker. Now you or your handyperson can cut the acrylic sheet opening using a jigsaw or a band saw. Also "round off" the four corners of the sheet with either the jigsaw or the bandsaw. Adjust the sheet so it fits the neck of your machine. Now attach the "legs" with wood screws. Now double check the height of the table to the neck of your machine. If it needs to go a little higher, I use pennies inside the caps to make the adjustment of the legs. Of course, if the legs are to long, you'll want to just cut them shorter. This makes an awesome sewing table that is wonderful. Now if you want a really large sewing table, Go to Amazon.com and buy 1, 2, or 3 2 ft x 4 ft adjustable height, folding tables and you will have a set up that will accomodate even a California king quilt for sewing on your domestic machine. Best of all, this is all portable and easily moved to wherever you need it. I had researched sewing tables, sewing cabinets, and everything in between. I came up with this combination and absolutely love it. I have four machines and I made acrylic tables for all of them. They each have their own "personal table" and when I need the super large work surface, I move the whole shebang into my family room and set up the folding tables around the machine wherever I need the support for the quilt. Good Luck and "Enjoy!"
