I think the hardest cards to make for a crafter have to be teenage boy's cards. Last month I had two to make, one being my nephews 18th and the other a family friend a couple of days after.
Luckly my nephew is a keen Star Wars fan so I came up with this card for his birthday, not your usual 18th birthday card but one he would like
The second card was this one
I am lucky that I have my Silhouette Cameo electronic cutting machine that I just couldn't do without now.
