Here’s what I just typed up for our Relief Society craft day on Saturday:
The cheapest flowers are found at dollar stores: Honk’s (on Freedom Blvd. in Provo) or Dollar Tree both carry them (currently Honk’s has more colors, while Dollar Tree carries lots of white and red). You’ll find larger, nicer flowers at craft stores such as JoAnn’s, Michael’s, or Robert’s (and you can use a coupon). Purchase alligator clips at Robert’s in smaller packages, or get them cheaper by buying a box of 100 at a beauty supply place such as Sally Beauty (which is around $5)
Use 3/8” ribbon to cover the clip. After cutting the ribbon, heat-seal the ends to prevent fraying by passing the ends near the flame of a match or lighter. To cover the clip with 3/8” grosgrain ribbon, follow the instructions at this site. The same information can be found in this YouTube video.
Unlike what it says at that site, I have found it works better to use Fabri-Tac glue than hot glue for this step. Also, if you want to cover the entire clip inside and out, use a 7” length of ribbon. I also do use shelf liner for the nonstick strip (also found at the dollar store) and I use hot glue to attach it.
Now, take apart the flower, discarding the stem and all the little plastic parts between petal layers. Wire cutters may be useful if the flower doesn’t want to come apart. You may wish to keep the central stamen parts. Next, glue the petals back together a layer at a time with a thin coat of hot glue. Glue the flower to the clip, and add a bead or button at the center. It works best to apply a generous amount of glue to the bead or button, then press it into place.
