This is based on an art piece from the 4 yr old grandson of a friend. I include a picture of both.Due to yardage constraints, the "art" section is enlarged to only 36x48. All the black crayon lines still need to be added, probably heavy black couched yarn.
I want to make it bigger and more useful as a lap robe for TV watching.
The colour for the boarder has me hesitating though I'm leaning towards solid black, a 6 to 8 inch addition all around.
Anyone else have any other suggestions so as not to compete with the centre?
