1. Use one wreath form from the Dollar Tree
2. Hot glue easter grass in clumps all along the wreath.
3. Follow up by gluing on plastic eggs.
4. Trim around the edges to shape. (And, I'd probably trim INSIDE the wreath too - which I didn't do for this photo obviously. Trimming inside would give it more of a wreath circle.)
Sidenote: This would also make a great centerpiece. Lay the wreath flat on the table and place a candle or tall vase inside with a floral arrangement.
