Lots of airy non super wash bobbins in muted shades and bold pink for the modules, and a shiny nearly black curly silk for the borders, - this color selection reminds me of a Harlekin.

-- Construction notes for my streamline Hydrilla --
Choosing the given “Alternative version” with smaller modules for a shawl of 192cm length and 64cm width (A 975m, B 720m)
Incr until 30% of A and/or 27% of B.

I am working a simplified B-Module, omitting the little tail at the end of each rib.

22 modules for waxing part, 11 for waning
92 sts at widest point.

!! Attention !! The instructions on page 9 for the waning part aren’t correct. It should be rather worked like written at the end of page 4. It’s a 2 row repeat, each module 16 rows in total and 8 sts decr (alternative version). The designer is planning to give an update.

Spine: Connecting the two half with an icord join across 5 sts, see https://youtu.be/OKhOTtls2q0. Going up to needle size 5mm.
Adding a crochet line on the back side.

190 x 90 cm (diagonal spine: 240cm)
