Easy to follow and well written pattern

I used anchored (negative) sts
Ch1 after the AS at beginning of each row, ch1 before AS at the end of each row for easier slst for the border

Main part:
Color A (multicolor): 314g
Color B (brown): 266g

Border:
Color A: 49g
Color B: 147g

Using hdc instead of dc for the back border rows 3 and 4 (because of the negative st)
