Ok, you're starting row 3, ch 3, turn, 2 dc in same st (photo 1)
photo 2, dc in each of next 3 chs,
photos 3, work FPdc3tog (Front post double crochet 3 together) around the stitches below. See, 3 were skipped on the linen row. The third part of the that FPdc3tog goes around the whole dc3tog from the previous row as if it is one st. (because it is!)
Photo 4, do it again.
Photo 5 Now working in the chains again, dc in the next 3 chs.
Photo 6, this is what the back looks like now. My finger is pointing to the unused chains behind where the FPdc3tog went.
Photo 7 back on the right side, 3 dc in each of the next two FPdc.
I'll do some photos on end weaving another day. Do you have questions about these photos?
