Any suggestions for 'left-handed white board'???

I'm sure there's some real 'Dragon's Den' great marketing thingy here somewhere, but just can't think of it!
DS is a leftie, he uses Yoro pens & Stabilo pencils for writing, staff really good at giving him slants to lift his books etc, but in Maths they do a lot of whiteboard work - always a problem, but this week he told me he'd rubbed out most of his working by the time he wrote his answer
There must be some way of getting round this for lefties??? The black smears on jumper sleeves are quite annoying too...

I'll watch the children at school and see if anyone has mastered it!

meanwhile, maybe the board being portrait rather than landscape? It would be less area to trail his arm across.

edited to add: just looking it up, one suggestion is board to the left of you and hand underneath what you are writing, this was for writing on the big white board , but might be worth a try
