My husband's sisters are both having baby girls this week, so I made them matching hats from Tonya Wagner's Little Boy Blue Ribbed Baby Hat pattern. I added some Slinky Crochet Flowers for fun. I like to glue my flowers on hair clips so they can be easily removed and used as a hair accessory when baby outgrows the knitted item.
Here is a picture of the back side of a flower so you can see the hair clip. I just hot glue it right on and it easily clips onto knitting.
