I also like F & P Love of Quilting ... More economically, I recently hit aq few estate sales and cashed in (cheaply) on bunches of old quilting mags, with far less adds and far more info.
But my main resource is the internet and EQ6. This I love and it is a tiresess resource for designing your quilts, boarders, sashing, etc. I started with EQ4 (after a year of researching this ... Hubby is a Puter Geek and helped with the research). This software is amazing and lots of fun to play with.
Good Luck and welcomr to the wonderful world of quilting!
