I like using Pinterest to lead me to quilting sites of interest.
For videos you can't beat YouTube! I have learned a lot from watching good YouTube instructional videos. They saved my bacon when I got a longarm and didn't have the first clue how to approach building my skills...I stumbled onto the "Michael Quilts" series and that made all the difference for me!
