Here's a really easy project you can try after school. (I bet you have all the materials already). We turned ours into notecards for family and friends.
You'll need: A potato or two (We used russets, but another kind will work; use whatever you have), a paring knife, paint, construction paper or card stock, a pencil or pen.
Step 1: Give your potato a quick wash and dry, then cut it in half. Cutting lengthwise will give more surface area for your stamp; cutting widthwise will give you a handle that's easier for little hands to manage.
Step 2: Using the tip of a pencil or pen, lightly scratch your shamrock shape into the cut surface of the potato. (If - like me - you're not happy with your first attempt, just slice it off and start again with a clean surface).
Step 3: Use a paring knife to carefully cut away potato from the edges of the shape you sketched. Are you really good at carving jack-o-lanterns? It's kind of like that, but potatoes are a lot softer than pumpkins.
Step 4: Blot your finished stamp with a paper towel, then press it into some paint and stamp away. (It might take a few tries to get the right amount of paint on the stamp).
Step 5: Let your prints dry. Then cut, fold, sign (and seal with a kiss).
