0 they work great.
MY EMBROIDERY SPOOLS WERE A MESS WITH THREADS TRAILING EVERYWHERE. I TRIED USING A SMALL PIECE OF BLUE PAINTER'S TAPE TO HOLD THE THREAD END TO THE SPOOL, BUT THE TAPE CURLED UP. THE THREAD SPOOL HUGGERS WORK GREAT ON ANY SIZE SPOOL! SO HAPPY I BOUGHT THEM!
They work wonderfully!
I really wasn't expecting much and was totally surprised by them. They are wonderful. The huggers really do hug the spools just as advertised. I am extremely pleased with my order!
