patterns?

[kidneypuncher.livejournal.com]

hey crafty ladies and gents, i need some help with a pattern. actually, i need a pattern for a purse. i've never made one, but today at a thrift store i found some great stuff i want to try with.

i got:
-a pair of pink and glittery pants (made of 75% polyvinylcloride and 25% polyurethane) [for the purse]
-a pink polkadot on pink polyester/cotton chunk of fabric [for the lining]

i have never made a purse, i'm willing to start with something like a coin purse or clutch, but the fun part is that i don't own a sewing machine (yet). are there any certain things i ought to know about working with fabrics like these?
