I just got a Pottery Barn Kids catalog in the mail. Each page is filled with great color combinations with all the hot spring colors and designs. I'm always amazed at how folks blend solids and patterns, etc. I'm only on page 14 and already have ideas for about 3 different cakes. Here is a link to the catalog request page at Pottery Barn.com. I'm sure others have already tapped into this, but for those that still could use some "free" inspriation, check it out.
