This is an ATC (2.5 x 3.5) that is part of the series of florals that I'm doing for an exchange. I used ink and watercolor crayons in this. Hydrangeas are a challenge because of all the little flowers clustered on each branch. I thought the wc crayons might make it a bit easier, but I think the smallness of the card made using them a bit harder. I may try another hydrangea in just watercolor.
