I googled grab ball pattern. There are several web sites. they are easy to make and got together rather quickly. I put rattles inside one of the sections. I save the bottle tops from water bottles and put 3 o4 4 buttons into one of them then tape the second one onto the first. I used masking tape and really wrap up the tops so they don't come apart. Then I put stuffing aroiund the rattle before I insert it into one of the sections of the ball. I have also put small jingle balls in the bottle caps and had some squeekers left over from some dog toys that I put in the ones I crocheted.
