there are a few on line shops that have a 'design wall' feature- where you can 'browse' their fabrics, add them to the design wall then look at them together, move them around, see how the relate to each other. fabric.com is one, I know there are many others- look for that feature when 'browsing' and try it out- playing with the fabrics might help. also, print off pattern pictures in black & white (like log cabins, stars, pineapples ect) and color with colored pencils or markers to try out the fabric colors you would like to try. there are sites that offer free (graph paper) you can print off- that comes in many different 'shapes' so you can design your quilt- in the colors you want.
