I first saw them on Pinterest [surprise] and made my own. The lady who did them on Pinterest made her's smaller, but I made mine as a half sheet of paper :)
Here's a pic, and click the link below for a FREE download!!
Step 1: Print the download onto cardstock so they're sturdier.
Step 2: Grab a few coffee sleeves from your desired coffee shop...obviously I LOVE Starbucks.
Step 3: Glue the coffee sleeve onto the thank you card.
Step 3: Purchase a Starbucks gift card [I'm just doing $5 because it could really add up] and stick the gift card into the coffee sleeve.
Step 4: Give to someone at your school that really helps you out!
