I started an autumn afghan, here's a photo. I've not written it down, so I'll just wing it and show you a close up and hope you understand what the heck I'm talking about in a pattern. :D
Ch 4 and join.
Row 1. Make 12 dcs in the chain.
Row 2. In between each of the 12 dcs make a leaf by joining 2 hdcs and a ch 1 between each leaf. So you'll have 12 leafs.
Row 3. In each of the ch 1 spaces crochet 4 dcs around. So you'll have 48 dcs all tog around.
Row 4. In between each of the set of 4 dcs, make a ch 4 loop around. So you'll have 12 chain loops around.
Row 5. In 1st ch 4 loop of Row 4 do 2 hdcs, 1 dc, 1 trc, 1 dc, 2 hdc and this will be a corner. In next ch 4 loop of Row 4, 2 sc, ch 1, 2 sc. In next ch 4 loop of Row 4, 2 sc, ch 1, 2 sc. In next ch 4 loop of Row 4, for another corner, 2 hdc, 1 dc, 1 trc, 1 dc, 2 hdc. Cont this around for 4 corners with 2 loops of 2 sc, 1 ch, 2 sc, between the corners.
Here's how I join the motifs after doing the 1st one...
I work the 1st corner of Row 5, then the two loops with the 2sc,ch 1, 2sc. For the next corner I'll do the 2 hdc, 1 dc and 1 trc, then slip stitch into the trc of previous motif corner, then cont on with the corner, in the next loop, I do my 2 sc, instead of the 1 ch, I slip stitch into the ch 1 of the previous motif worked, then the 2sc, etc. around. I like joining my motifs together, some people just sew them together afterwards.
