We put our candies in for 6.5 minutes at 325 degrees. They had spread enough at this point, but they continue to melt a bit from the heat of the pan after you take them out, so 6 1/2 was an ideal time for us. (Better to take them out a bit early when they still have shape and substance, rather than too late when they're flat and runny.)
We left the wreaths to cool for a minute, but since the flower didn't have a hole, we pushed an ornament hook underneath it while the candy was hot and soft. (Make sure not to touch it with bare fingers!) Note: If your wreath breaks, try putting it back in the oven for a couple of minutes; usually the candy will melt back together.
