Scallop Variation and Small Scallop Variation 1
These two wave-like stitches are related. Note that Scallop Variation (above) is made up of two different rows.
Small Scallop Variation 1 repeats all the rows, although they are offset so that the peak in one row is under the low point of the row above it.
Both make nice water, sky or clothing stitches.
