I’ve had my Denise needles for a couple of days now. First impression of the resin needles is I like them. They are VERY light and smooth.  The yarn does not glide across them as easily as my nickle plated needles, but it does glides across much more easily than acrylic or bamboo needles. I am happy with the points. I’ve been able to easily k2tog. The cords are thicker than I’m used to, but I haven’t had any problems with that. I’ve been able to do the magic loop method with them no problem at all. I’m also not having any problems with the joins. The yarn glides past them easily. Add to that the fact that they are made in the USA and have a life time guarantee. These needles are a great investment.
