Sorry I'm not a huge help but I found that my toddler at 18mths loved drawing with thick chalk on the backyard concrete path & inside drawing on a big paper pad with thick crayons (89c a pkt from Go-Lo or The Warehouse) & drawing on a sketch-a-doodle ... & painting with a brush dipped in water on concrete too

... and when she turned 2, yeh out come the play-doh & crayola washable textas for little hands - Texta marks come out of clothing in the wash - Brilliant !!! ($3.99 a pkt of 8 textas from Target)

I'm starting to run out of ideas myself for my 2 year old for indoor arts & craft for this Winter season
