I own the Denise set and I love love love them!!! I have never done Magic Loop Knitting, but the cords on the Denise are thin and very pliable. I would imagine they would be ok... but don't quote me. Either way, they are the best thing since sliced bread!!!
On the Needles: Calla Tank (Magknits.com) and a baby blanket for my co-worker
Next on the Needles: My own design!!!
