How to Crochet a Beanie
It was too boring so I added a couple rows of seed stitching to the bottom in hot pink. I use a lot of seed stitching in my projects to add decorative texture to things. The seed stitch is a very simple stitch since it is just basic stitches being alternated. You simply single crochet, then double crochet, then single crochet, etc... When you reach the end of the row you turn it around and double crochet on the single crochets and single crochet on the double crochets from the previous row. You could also do triple/treble crochets instead of double crochets for even more texture.
Here is a great page I've bookmarked on how to do a variety of fun stitches: Crochet Stitches and How to Make Them (Although seed stitch isn't on this list, which is why I explained that one!)
Even with the pink border I thought this hat was too boring for my little girl, which is when I had this vision of it covered in colorful butterflies. So I went on the hunt for a simple butterfly pattern and found this one: Crocheted Sass-Butterfly Pattern
These butterflies were quick and easy to make so I made several and just tied them on the hat with yarn. I can see myself making lots of other butterflies in the future for various projects to use as embellishments.
