Ohhhh, the dreaded hunt for good flannelete flats! I have just done it!! Target sells the Big Softies brand which I believe are the only ones worth buying. I wanted two packets (they come in packets of 12) and could only get one at a time. They sell out super fast! Maybe ring around a few stores to see if they have any in stock so you don't have to waste time going there to find none. Not sure about the snibs, what about the Chemist Warehouse??

Hope that helps!
