Shopping Our Stash has done a fabulous job of creating "my nemesis" One Layer Cards, I think I do one or two every year and always for a challenge for the design team. I'm totally lost when I can "add" more and more but I bit the bullet, took one for the team and made a One Layer Card!!!
For my card I used Very Vanilla cardstock, Tim Holtz distress markers and Inspired by Nature set from Stampin'up to create a watercolour look (I hope)
The sentiment is from the same set but the butterfly is from a different Stampin'up set called Nature Walk (retired) and coloured with the distress markers.
