Recently 'The Quilt Show' started some basic lessons for new quilters. Piecing 101 with Alex Anderson is a series of short videos made by Alex Anderson. A lot of knowledge is shared so if you are a beginner or just want to brush up on some skills check them out.
Here's a few lesson names to give you an idea of what is covered. Stocking Your Tool Belt, Fabric Grains, Prewashing????, Rotary Cutting & Fear of Fractions, The Art of Pressing, Pinning, and more.
You do need to sign up for a free membership to use these beginner lessons, but it is worth it as there is a lot more free stuff to access. Check out the free show under 'Watch Shows'. Also have a look at the 'Projects' and 'Quilt Gallery'.
