This was a sun set that I put together for a friend's grandbaby.
The t-shirt was purchased and already had the little tucks down the center front. I added a fabric ruffle to the bottom hem and made the bloomers. The hat edge was bound in the same bee fabric.
The wings on the bees are silk and organza ribbon held together and stitched like this example. (click images for larger details) The detail of the bees and "honey" were stitched free motion.
