I decided to "fill in the gaps" and make some half hexies for the sides.
I Googled around and looked at Ravelry hexagons, but could not find any thing that would work.
No Pictures available - somehow they disappeared from Flickr
Only one available is on Ravelry
This is how I made up the half hexie.
R1: 8 dc in a ring (however way you want to make the ring, I did a magic loop) Break yarn. DO NOT TURN
R2: Ch4, (2dc cluster in next DC, ch1) repeat 5x, ch1, dc in last dc. Break yarn do not turn.
R3: Ch3, dc in ch1 space, (ch1, 3dc’s in next ch 1 space) 5x, ch1, dc in ch1 space, dc in last dc. Break yarn.
R4: TURN hex motif to wrong side and start this row with a sc, ch2, (sc, ch3) 5x, ch2, sc in last stitch, TURN
R5: Ch4, 3dc in ch2 space, (3dc in next ch3 space, 3dc, ch2, 3dc in next ch 3 space) 2x, 3dc in next ch3 space, 3 dc in last ch2 space, dc in last dc.
Hopefully I typed this out right, but if in doubt you should look at the pictures.
Since I did not take a pic of the last row on the 2nd attempt, I do not have a model to go by. It fit so well I did not want to take if off the blanket ;)
So there might be an error on the last row - let me know :)
Which ever way you choose to make your half hexies fit is probably ok as long as they look good on your blanket!
