Eleanor Burns book Still Stripping is full of strip ideas or look up Quick Quilts in a Google search. Teresa down under has free video patterns,
www.quiltcache.com has over 1600 free patterns. Moda and other main fabric productors have free patterns on their web sites. Some are always for the beginner quilters for quick quilts. I do agree with the others on their ideas, and tutorials are available on QB section of tutorials.
