Brenda K - the snaps are very easy and no sewing needed. Each side has prongs and a washer so you make a tiny snip in the lining fabric and trap the fabric between the two parts. I also reinforced that part of the fabric with a scrap of fusible fleece. I bought a job lot cheap from China on the website named after a long river.
costumegirl the octopus was part of the pattern but I adapted it slightly
