Here's a sketch from Crafty Steals Blog for a Christmas in July contest. You had to use a Winter/Christmas theme.
And here's my take on it. I used my Silhouette sketch pens in silver to draw the trees. The pennant and snowflakes are silhouette images. I used black letter stickers for the "let it snow".
My lesson learned: My white sketch pen that came with the set does not work. I tried to do the trees in white (several times) and it just wasn't working. I switched to silver and it worked the way it was supposed to. Guess I'll be contacting customer service about my white one. They have very good customer service I know. Hopefully I can do an exchange.
