Rainbows have always had many meanings throughout history. Since the beginning of human civilization, we can find rainbows in ancient myths and folklore.

Nowadays, rainbows and rainbow flags mostly symbolize LGBTQ+ pride (or peace, if you happen to be in Italy!).

But most importantly, rainbows can signify something different for each one of us and carry with them hope and calm at the end of stormy times.

This is why rainbows have also become a symbol for rainbow babies. A “rainbow baby” is a baby who is born after a miscarriage, stillbirth, neonatal death, or infant loss, and after all the sorrow and grieving, he/she brings back some color into his/her parents’ lives!

Whatever your reason for crocheting a rainbow blanket, here you can find 29 free crochet patterns for rainbow blankets. These blankets are perfect as a rainbow baby gift idea, for commemorating Pride, or as a bright and magical piece of home decor!

What are the colors of the rainbow?

The colors of the rainbow are red, orange, yellow, green, cyan, blue, and violet.
