Creating a sphere in crochet involves working in continuous rounds to achieve a seamless and smooth finish. Below is a simple crochet pattern for a small sphere. This pattern assumes basic knowledge of crochet stitches, including single crochet (sc) and increasing.

Materials:

• Some yarn you like
• Crochet hook that feels right for your yarn
• Fluffy stuff to fill it (polyfill or whatever)

Abbreviations:

• sc: single crochet
• inc: increase (work 2 sc in the same stitch)

Pattern:

1. Start with a magic ring.
2. Round 1: Work 6 sc into the magic ring. (6 sts)
3. Round 2: Inc in each st around. (12 sts)
4. Round 3: (Sc, inc) x6 (18 sts)
5. Round 4: (Sc in the next 2 sts, inc) x6 (24 sts)
6. Round 5: (Sc in the next 3 sts, inc) x6 (30 sts)
7. Round 6-10: Sc in each st around. (30 sts in each round)
8. Round 11: (Sc in the next 3 sts, dec) x6 (24 sts)
9. Round 12: (Sc in the next 2 sts, dec) x6 (18 sts)
10. Round 13: (Sc, dec) x6 (12 sts)
11. Round 14: Dec in each st around. (6 sts)
12. Finish: Fasten off, leaving a long tail. Thread the tail through a yarn needle, weave it through the front loops of the remaining 6 stitches, pull tight to close the hole, and secure the end.
13. Stuff it: Fill it up with fluff until it feels right to you.

Feel free to mix it up! Change colors, try different stitches, whatever floats your crochet boat. This pattern is a basic guide, and you can experiment with different stitch patterns or color changes to customize your crochet sphere.
