I have a set of Denise Interchangeables and I LOVE IT!!!!!!!!
My very 1st set of interchangeables was a Boye set and they worked for awhile, but the Denise set is a HUGE step up from Boye!!! That being said, I have noticed that the cords are "thicker" than the Boye ones and sometimes it's hard to move my 100+ stitches around them row by row.
But overall, I really like them!!!
