super easy recipe from Pocketful of Motherhood!
Photo Coasters: We made these photo coasters a few years ago and I loved how they turned out. You can read the tutorial here. They are made out of cheap shower tiles from Home Depot! You could also have students decorate the coasters with sharpies like this tutorial explains here.
Hot Chocolate Cones: Who doesn't love hot chocolate and these are simply adorable! Photo credit and recipe found at Simply Jessica Marie.
Sharpie Mugs: I love the idea of using a sticker outline so that kids can scribble to their hearts desire, and it will look super cute when the sticker is taken off! Of course, you could have your students create their own designs as well. Tutorial and photo from Messy Little Monsters. (She uses a porcelain pen, which is great, but if you don't have them, I've heard other people have great success with Sharpies!)
Of course, ornaments with photos are always a big hit too! What are some of your favorite creative parents gifts?
