|The flowers are removable, so you can 'plant' and 'pick' them.|
1) Cut dowels to desired length. Sand the tips.
2) Attach flowers to dowels with hot glue gun.
3) Cut wooden board to fit the flower box (we had this already).
4) Drill holes in the wooden board to fit the flowers. Make sure you can get the flowers in and out with ease.
This whole project cost me less than $4. The dowels were all that I needed to purchase. I was fortunate that the lumber yard gave me scraps of wood to play with.
