1) If you would like to use fresh gerberas, you can purchase them in bulk from a wholesaler such as http://www.fiftyflowers.com/flowers/AllFlowersGerberas_126.htm. Purchase some floral sponge letters like these (http://www.adams-packaging.com/acatalog/oasis-foam-letters.html), float them overnight in water until they sink to the bottom (this means they are holding water) and insert the cut daisies into the floral foam. Do note that the gerbera stems are fairly weak, so it would be a good idea to leave the plastic stem enforcers that come on gerberas on them as you insert the stems into the foam.

2) Using fake gerberas. Make sure you do splurge on some nice ones; fake gerberas do tend to look, well, fake, so unless you get some very nice ones it might end up looking tacky. Save on Crafts is a nice site with some listed, link: http://www.save-on-crafts.com/gerberdaisies.html. Use letters like the ones I used in the moss project above, which can be found at a local craft store, and I would also recommend spraypainting the letters the same color as the gerberas to prevent the white of the wood from peeking through. Then hot glue the heads of the gerberas onto the letters, attach the ribbon of your choice, and you’re good to go!

Hope that helped!
