Here is what I came up with:
These mandalas were done with basic crochet stitches, which make them quick to stitch up!
The rose mandala was done using Drops Paris yarn #14 strong yellow, #11 opal green, #6 shocking pink, #33 medium pink, and Acaucania Ulmo Solid #767
Even though it is hard to see in the photo, this mandala was done in an aqua and light blue, the light blue seems to blend in with the green. The yarns used for this blue mandala were Drops Paris yarn #14 strong yellow, #11 opal green, #2 light turquoise, #06 shocking pink, and Acaucania Ulmo Solid #767
If you would like to make a few of these mandalas to brighten up your house or to give away as gifts you can access the pattern here
