The first time I tried a dropstitch pattern – unfortunately I have forgotten which one (this was made back in 2013). A quick search on Ravelry and nothing familiar showed up although they had various ‘Seafoam’ dropstitch scarves.
Yarn is GGH Goa (#101), 50 % cotton and 50 % polyacrylic, 250 grams, 5 mm needles.
A drop stitch pattern is made by yarning over several times according to the pattern before you knit a stitch and then you drop the yarn overs in the next row. Sounds frightening at first.
