Review on New Brothread Machine Embroidery Stabilizer Sewing by Summer Hendricks

I tried the above battings and some of the 40 spools of thread as soon as I got them and they work fine. It was a nice surprise to get some spool nets to keep the line from unwinding too quickly during use.*** The only thing I didn't understand was where the line end attaches to the line spool. so it doesn't fly off the spool when not in use? There doesn't appear to be a small gap along the edge, nor an extra edge for the end of the thread to wrap around. I hope the 40 spools don't fall apart when stored on my spool stand.
