Denise needles size 6

[dturner]

I purchased my Denise interchangeables a little over a year ago when I started knitting. I just noticed that I seem to have two sets of size 7. I am using the Knit Picks needle sizer, but I assume they're all the same. Have any other Denise users had that problem? The needles that are marked 6 will not fit through the US 6 (4mm) opening at all.
