It’s a wreath of yellow roses, set afloat in a pond. More roses are strewn in the grass where we sat making the wreath. A game! See if you can throw a rock into the wreath. Yes! Bulls-eye! PLORK! the rock went, splashing water up in the center!

I LOVE this granny - this designer is extremely talented, and her other squares look fascinating! If the pattern corrects some errors, my diff rating for this would be Easy.
Notes:
On some rnds, when pattern says “sk 1st sc in next dc”, it should say “sk 1st dc, sc in next dc”.
Rnd 12 error: when instructed “sk the very first dc”, the pattern as worked skips the first 2 dc.

Re-wrote Rnd 12, keeping w/pattern but adjusting st height to square up, and correcting error as stated above; hopefully I haven’t made any of my own errors too but since this block is so great I’ll make another one and find out:
Rnd 11: My st count after completing - {120 st + 4 ch-2 corner sps (30 st each side)}.
Rnd 12 (re-written rnd): With CC, sl st in any ch-2 corner sp to join, ch 3 (counts as 1st dc), dc, ch 2, 2 dc in same sp, { #ch 1, sk 1st st, dc in next 6 st, hdc in next 2, sc in next 3, ch 1, sk next, sc next, ch 1, sk next 2, sc next, ch 1, sk next, sc next 3, hdc next 2, dc next 6, ch 1, sk next,## (2 dc, ch 2, 2 dc) in ch-2 corner sp} three times, rep between # and ## once, sl st in 3rd ch of beg ch-3 to join – 132 sts (ch-1 sps count as a st) + 4 ch-2 corner sps: (33 sts each side).
Rnd 13 (written keeping w/pattern, adj. for Rnd 12 st count): Note: Work in front of ch-1 sp unless otherwise noted. With CB, sl st in any ch-2 corner sp to join, {ch 2 (counts as 1st hdc), hdc, ch 2, 2 hdc} in same sp, three times, rep between # and ## once, sl st in 2nd ch of beg ch-2 to join – {136 sts (pcs do NOT count as a st) + 4 ch-2 corner sps (34 sts each side)}.
Rnd 14: As written, except (sc, ch 2, sc) in corners - {144 sts + 4 ch-2 corner sps (36 sts each side)}.

To get to 9” size added two rows:
Rnd 15: {(Sc, ch 2, sc) in corner ch-2 sp, (ch 1, sk st, sc in next st, ending in sc before corner} around - {152 sts (ch-1 sps count as a st) + 4 ch-2 corner sps (38 sts each side)}.
Rnd 16: {(Sc, ch 2, sc) in corner ch-2 sp, sc in each st and ch-1 sp to next corner} around, sl st to 1st st to join - {160 sts + 4 ch-2 sps (40 sts each side)}
