Crochet Applique on Crochet Blanket?

I have started crocheting a blanket for my own personal use. I have a decent start and don't want to start over, however I have a brilliant idea for a theme. Is there a way to attach a crochet applique to the blanket or can I stitch on the top of it and have it look good? Links with directions (or typed directions) is what I am looking for. I don't need patterns. Just the best way to add to the blanket when I am done. Thanks.
