If you don't want to sew the foe bands you can use fabric-tac for both of those styles. I cut the bands to size, heat seal a bit and use the fabric-tac to glue them. I use a those really strong paper clips that have the metal flaps to pinch them open to clamp them down tightly while they dry. Once there ready, I just add my flowers and use my glue gun to attach the flowers to the bands and use a felt circle to glue to the inside of the headband for extra hold and comfort.
There's a ton of help on here, use the search link, chances are 5 other people have already asked what your wondering.
Hope I didn't confuse you even more...lol
