I've been looking around for the best price on a sewing machine extension table. I have come to realize there is no "economical" commercially made version of any table. They range from $50 and up - that's if you can find one to fit your make and model of machine. Or you can have one custom made for about $70
So I thought to myself there must be a way to make one myself. I drove to Lowe's and checked out their selection of acrylic sheets. For about $13 you can get a 1/4" thick acrylic sheet that is about 24"x 24" in size. You can then cut out the opening for your machine using a scroll saw. I didn't check but they might even be able to cut it for you there. Then you'd have to sand your cut edges smooth to prevent the fabric from getting caught. Some masking tape or blue painters tape on the edges would add some additional smoothness. Alternately you could look in the phone book and have a glass cutting place cut out the opening for you.
Then you would have to use something for the legs that would raise the table to the correct height of your sewing machine. My husband suggests wooden dowels cut to size and counter sunk into the under side of the table. Attached with? glue, screws? - I don't know
I have yet to try this theory out but will let you know when I do. Probably sometime in February since the budget for this month has already been set and did not include a "sewing machine extension table."
I also found this DIY version online:
I might just end up doing it this way. I don't really see an advantage to a "clear" table. Another option would be to use wood shelving so that you can router your edges so they would be curved and smooth.
