Tab cast on drove me nuts! It was far too fiddly!
Instead, I cast on 6 stitches, knit 2 rows. On the 3rd row first stitch I knit the front and back, knit 4 stitches, last stitch I kfb again. Ta da, 8 stitches and ready to start rest of pattern.

First stockinette section and one lace repeat done, 34.5g remaining.

Second lace section done, 22.7g remaining. So I’m using about 11.8g per full lace repeat.

Yay finished! I ended up working 2 full lace sections + 12 rows. 18 rows stockinette (including increase row) then the 4 ruffle rows as written. Worked my preferred YO bind off.

I love using my scale for knitting. I was able to estimate the amount of yarn required to get 18 rows + ruffle with minimal leftover and maximum lace. After weaving in the end. I have 125 cm of yarn leftover. HIGHFIVE!

I flipped my chart so the decreases would be K2TOG instead of SSK just like Isamight did!
If you have Adobe Photoshop CS5 it’s super easy. Just select the chart (but not the row numbers, just the charted part only) then Edit > Transform > Flip Horizontal. This flips only the selected area.
