I pulled out the Hello You Thinlits and die cut four "happy's" from Whisper White card stock and adhered them all together using Tombow Mono Multi. My favourite adhesive!! I added sponged colour to my background base card and then heat embossed my sentiment in white embossing powder. Once I die cut the oval window from my card front, I used dimensionals to adhere it to my card base.
I then adhered my layered die cut over the oval opening and used Tombow again to adhere it to the sides of the oval. Having four layers to the word gives it strength and allows the word to float above the oval window creating the awesome shadow behind. Try it yourself!
