Butterflies come in all shapes and sizes, and that's a good thing! To make one, use the mother's favorite colors, or match the diaper cake so that it coordinates with the nursery or with the color scheme of the baby shower.
Just as you can purchase silk flowers, you can purchase silk butterflies to use as embellishments on your diaper concoction. Check out your local craft stores. If the selection seems slim locally and you have enough time, do an online search. There are many online stores that sell them for a good price, and it's amazing how realistic they look! You may also want to check out scrapbooking stores for butterfly die cuts and stickers. If all else fails, you can even make your own using coffee filters and clothespins or tissue paper and pipe cleaners.
Other embellishments may include silk flowers, paper raffia, and die cut letters spelling out the baby's name. Don't forget to tuck a few toiletries and toys for the little one in the layers and tiers of the butterfly diaper cake.
