Teresa Down Under does nice tutorials, I like the square within a square. simple. easy. Cut out a square of flower, animal or whatever is a favorite of the receiver use it as a square pattern to cut the next square. Mark an 'X' on it and sew around all four sides. Carefully cut out the 'X' pattern but do not cut the square you started with. Repeat as many times as you need to get the size that you want. Use colors that relate back to what you started with in the first square.
Then there is the
www.quilterscache.com that tells you how easy or hard each block is, and it is free to use. Judy Martin also has free patterns and Fons and Porter has a magazine called "Quick Quilts" or visit their site. As does Moda and other main designers names. Good Luck, its hard for me to choose sometimes.
