All of our patterns are tested with 3" foam balls so we don't have exact directions for other sizes. For that size, you could add 1/4" to your fabric cuts to help cover more foam. You can also use more layers of fabric as you get to the equator of the ball to help cover everything. Happy Ornament-ing!
You can try adding 1/2" to the fabric measurements. You may also need to play around with the spacing of your fabric to get the look right. I hope you'll give it a try!
All of our patterns are designed for 3" foam balls, but you can easily adapt our patterns by using a little less fabric. We don't have an exact calculation, so you may need to experiment a little bit. You can also find 2" foam balls in our supply shop here: theornamentgirl.com/market/product/2-inch-soft-foam-ball/
