Oh...I wasn't done.
As far as being serged on 3 sides, I'm not exactly sure, they are more cut off than anything else. They are just in these large books people can look through when decided what they want to reapolster their couches or pick curtains as some of these are pretty see throughy. But the labels are applied with really heavy duty furniture glue and they go all the way across the fabric on the wrong side of the bottom. On the top, front and back is more glue and the holes from the heavy duty furniture staples that I had to remove. I tore muscles I didn't know I had separating all those pieces!!
