Finished in the early hours of this morning and blocked today. I did 3 extra repeats but I think if I use the same yarn again (I have more in 2 different colourways), I would do more repeats or perhaps use slightly larger needles.
Here it is unblocked - approx 34 1/2 in wide and 15 1/2 in deep.
And here it is blocking - final measurements 49 in wide and 21 in deep. Being part of the KAL has been great and ensured I got this completed!
