I created this card using American Crafts XOXO collection. I got this idea in my head but it was a bit of trial and error to actually design and execute this card. Here are the details:
I started with a 4 1/2 x 12" piece of cardstock which I scored at 4 and 8" and then folded. For the engine I actually created the template myself but you could probably make it easier on yourself and find some clip art online to print and trace. My adorable train engineer is from My Mind's Eye's Alphabet Soup Boy Playing Cards.
For the wheels I punched circles out of patterned paper (love those little arrows!) and adhered them to cardstock circles (a must if you want the train to be able to stand up on it's own). I used 3D foam squares to adhere them to the train cars and then used a border sticker to create coupling rods.
For the two train cars, I cut the cardstock to just 2 1/2 " high. Then for the middle car I adhered a piece of white cardstock and attached several sticker, die cut, and layered heart embellishments.

For this last train car, I attached a piece of black cardstock which I trimmed with decorative scalloped scissors...I was thinking coal. Then I just adhered the xo Thickers. Obviously I covered all the main bodies of the train cars with patterned paper and various stickers/diecuts.

I love how this came together. Wouldn't it be fun to add 2 more cars and a caboose?! I might give it a try and use this as Valentine decor...I'm thinking it will look great on my mantle next Valentine's Day! And I just got some of the BoBunny Surprise collection so maybe I'll make a birthday train next!
