Skip the next 3 chains, SC in the following chain.
Repeat:
Skip 3 ch, [3 DC, CH 1, 3 DC] in next ch, skip 3 ch, SC in next ch.
Continue to the end, pulling through the final stitch with Rice Paper (cream).
Row 2

Skip first SC. Work DC3TOG over the next 3 DC.
CH 7, skip 1 chain, DC6TOG over the next 6 DC (leaving the SC unworked).
Repeat from * to * across.
End by working a DC3TOG over the last 3 DC, then DC into the top of the turning chain.
Row 3
CH 3, turn.
Work 3 DC into the space formed beside the DC3TOG.
SC around the CH-1 space of the row below, enclosing the CH-7 loop.
In the center space of each DC6TOG cluster, work [3 DC, CH 1, 3 DC].
Repeat from * to * across.
At the end, work 3 DC into the space near the final DC3TOG, then DC into the turning chain.

Repeat Pattern
Continue repeating Rows 2–5, switching colors as desired and following your diamond layout.
For the final half-diamond row, where a CH 7 would normally be used:
→ Replace with CH 3, SC around the stitch below, CH 3.
This adjustment helps prepare the blanket for working an even row of DC around the edge for your border.
Finishing
Weave in all loose ends with a tapestry needle.
Add your favorite border style—DC, post-stitch ribbing, or a simple SC edging looks beautiful with this pattern.
