The pattern called for Blue Sky Alpacas worsted cotton. I couldn't find any in my local shops and didn't want to purchase it online without knowing what it was like, so I substituted Debbie bliss Rialto aran. I was really pleased with this choice as it is very soft and washable. I had quite a bit left over from 10 50g balls.
The pattern knitted up quickly, after I had to restart about 15 times, as I was automatically doing a knit stitch after every yarn over and getting very confused. Once finished it required a good press with a bit of steam which was essential to make the most if the pointy ends as they tend to curl.
I can imagine this pattern for cushion covers or a large throw.
