It is so worth it...If you have a sewing table where your machine sits down in your table, you don't need one, but if you sew with your machine on a table, it gives you a lot of flat sewing surface. I use mine mostly when I go to sewing days with my friends, or for retreats. But sometimes I like to sew in my dining room instead of my sewing room...there is a great view, and I use my acrylic table then too.
