I made this sweater for my Husband’s birthday this month. It turned out great! The pattern comes from the Craft Yarn Council’s website here. Instead of white yarn, I used Fishermen’s Wool from Lion Brand in “Oak Tweed.”
I’ve made this sweater three times now and it is still the most difficult pattern I have ever used. The cable stitches in the Celtic Knot are challenging themselves and are created by using front-post double crochets, skipping stitches and working in front of or behind previous stitches to pick up the skipped stitch. But it is difficult to follow the pattern itself as well as some of the raglan shaping is not very clear. I need to just rewrite this pattern for myself.
In addition, the pattern for the Celtic Knot itself is actually not accurate. The 
knot is supposed to weave “over-under-over” or “under-over-under” for each cable. However the given pattern does not do this. Some of them go “over-over-under” and vice-versa, and even “over-over-over.” They have actually updated this pattern since the first time I found it on the site and it now includes a diagram of how the cables are woven for the knot. It appears, according to this diagram, that the given pattern is intentional – not a mistake. 
Fortunately, I have another pattern book with cable patterns which includes this same Celtic Knot – woven correctly. So I worked from both patterns as I made this sweater. I actually did not even realize that the pattern for the knot was incorrect until this time around. I must have made the previous two “incorrectly.”
But regardless, my Husband has a new sweater – challenging or not. And I have to say that it looks great on him! Happy Birthday Baby!
