These are not hard. If you have mastered double and treble crochet you will not have to make a great leap in skills to make these crochet roses. They can be used to embellish all sorts of things or used on their own as decorations. They look especially nice in variegated yarn or if you use a block colour and then just slip stitch around the edge with a contrasting colour. There is a nice pattern on the Whoot for crocheted roses.
