This is an easy pattern. Circles are easy to crochet in general in simple dc, sc, etc.: just keep increasing groupings one more stitch farther apart for each and every new row and the circle should lay flat even if you keep going like that for forever.
The Ever-Gorgeous Christmas Tree is cute, realistic, and easy to work up. Just like your real tree, you can decorate this miniature Christmas tree pattern with beads or sequins to fully complete the look. You only need single crochet for this!
