Start with three wooden heart cut-outs and a rectangular piece of wood. You should be able to find these at most craft stores; I found mine at Michaels. Start by giving everything a coat of green spray paint.
Next, screw a small eye screw into one end of your wooden rectangle. This will give you a place to hang up your piece later.
Lay out your pieces into the appropriate shamrock shape. Now, hot glue the hearts onto the rectangle.
Cover everything with a nice coat of glitter. I used the green glitter paint shown below.
Next, you will need some wooden letter to spell the word "Lucky." Start by painting these with a coat of yellow-gold paint. Then brush on a coat of Mod Podge and cover with gold glitter.
Once dry, attach the letters to your shamrock using hot glue. You're almost done!
The final step is to tie a piece of twine through your eye screw in order to have something to hang your shamrock up with. The length will be determined by how low you want the shamrock to hang on your door.
Done! Now hang up your wreath and get ready for St. Patrick's Day. Corned beef and cabbage, anyone?
