hello, my name is Lauren (i am new!), and i'd much appreciate some help from you crafty folks :D you're all just so darned creative and knowledgeable!

i'm going to make a bag out of vinyl, but before i start and then realize i'm doing it all wrong...should i be reinforcing it with cloth or are there any other tips you might be able to give me? i've never sewn vinyl before and i'd like to keep my frustration level low on this project.
vielendank!
