I don't already have a polar bear pattern?!?! shocking I know, but here is a lovely bear a festive sweater. You could knit him in any colour you like real and he could be any sort of bear. This chart only requires 4 colours but you could get away with 3 and leave the background white, the bare outline will show him off fine.
Chart shown in picture knitted on my adult chunky base sweater.
Yarn colours required - MC: Green, CC1: White, CC2: Black, CC3: Red.
