This is the Nurmilintu shawl pattern by Heidi Alander. It’s a free download on Ravelry. In the first lace portion I was off in my count, so the pattern shifts in the middle. I am better at written instructions than charts. I wrote out the repeat portion and counted very carefully. The next lace sections went off without a hitch.
This shows the “tree” patterned lace up close.
Unfortunately, the striping of this yarn causes the lace parts to be less visible. I’ve started another shawl with solid yarn.
