The Beanie for this pattern is crocheted using two strands of 4 ply wool crocheted together. The scarf is crochet using a single strand of 4 ply wool. You could use an 8 ply for the hat and 4 ply for the scarf provided the same colours are available in both plys.

There are video tutorials on the various stitches used in the pattern. The tutorials can only be viewed whilst the pattern is online, so can be watched prior to printing the pattern off. All you need do is click on the stitches you need to view.
