So, I tried another sticker card with basic stickers. Flat, shiny, boring, round stickers . The card I ended up with is prettier than I expected.
I first cut up my sheet of Colorbok stickers so I could plan which stickers I wanted to use together. I used four of 18 and the others are grouped also, so I'll have sets when I get a chance to use them.
I mounted the individual stickers on cardstock borders and found a coordinating piece of paper and card base. I think the result is a gender neutral card (if men would use the sentiment "special friends") and looks better than the cheap stickers. Note: the card is not pink! It's an orange-red color but the camera didn't capture the color correctly.
