Share 'Have you sewn every pattern in your stash? Or do you hoard for a rainy day?'

Hello All! I'm curious on how people treat their patterns. So time to confess... Do you buy a pattern for a particular project, buy everything for it and sew it all up before you buy another? Or do you buy 20 at a time and keep them until the day you find the perfect fabric or inspiration to recreate it? I am the hoarder type... I have plenty of patterns unopened! Shameful I know!
