The kit has been discontinued, but you don't really need a kit anyway. The wire and hooks are readily available. The yarn is Jamieson's Shetland Spindrift. The color is Oyster. There are a number of places where you can buy it online. Feral Knitter has it in whole balls and also in 20 yard mini-skeins. https://www.feralknitter.com/product/290-oyster/
Step by step tying instructions are here. The instructions show my version of the Killer Bug, which is tied with a different yarn and which I color with a Prismacolor marker. The Utah version does not require the marker.
