I put a small table behind my sewing table when I need an extension. I have two tables. I have a Gidget table with a drop in it for the sewing machine (my machine is an older, smaller one so I filled in the gaps with a plastic place mat I cut up). I paid around $125 for the smaller Gidget table. The other is a Sauder table, I got it at Walmart and they do go on sale frequently for $99. It doesn't have a drop in although my husband said he could probably rig one up for me.
