This mandala is for adventurous beginners to intermediate.
Some stitch placements are a little tricky, but I tried to put pictures to clarify those placements and I put a little reminder for the more difficult stitches like the treble or popcorn.

The finished mandala is 12 inches (30 cm) without blocking or stretching.
Of course, you can choose any weight you like but the dimension of your mandala will change.
