I crocheted this pokeball applique for my son after trying to use a graph pattern to make one and having no success making a perfect circle.
It's done in rounds and is really very easy, and you can sew it onto anything! I crocheted him a beanie hat to put it on, and am planning to sew some on his storebought mittens too.
WW yarn in red, black and white
Any size hook will work to get the size applique you want, I used size f 3.75
You can make it any size you want by using the proper hook, depending on your gauge, and adding rounds if you like/
It takes 5 rounds to make a small one.
Besides using a larger hook, you can also make the applique bigger by adding rounds of white, red, and black/
You can find the pattern on my blog
