Calling all crocheters

[IDugUpADiamond]

I've searched high and low (e.g. Ravelry, Pinterest, etc) for this pattern but can't find it anywhere, only the whole cushion to buy on Etsy. I know how to crochet a round cushion but I need to know how to crochet the star and then the bits around it. Happy to pay for a pattern of course. Any ideas anyone?

here is a tutorial for a crochet star in a circle. Then you can just keep increasing until you have the size you want?

this and this pattern starts with a star in a circle or cheat and applique the star on afterwards
