Pom Pom Yarn for WUA Blocks

Yeah! My store donated Pom Pom yarn for the WUA Stitch In! Unfortunately, they did not schedule me time to figure out a 7x9 pattern, nor am I allowed to take the yarn out of the store. I have never worked with the yarn before and I expect I will be busy since I am doing both the WUA and MITI. Can anyone give a gauge guideline and stitch count for both knit and crochet?
