Replying to Is the seersucka fabric one layer or two?

I'm gonna try and make a crew this year for summer out of seersucker material, cause I like the feel of longsleeves in the summer, but don't want to bake in the heat. I just have one question, is the fabric on the Jiberish seersucka one layer or two? is that why there is stitching across the middle, to keep the two layers together? Because when I went to my local fabricland today, the material seemed way too thin to make a hoodie out of. Help me out please

good answers +k
go ahead and give shitty answers if you want, but don't tell me to use the searchbar, I have.
