Some ideas:
1) Buy cheap candles and glue ribbon in your colors around them.
2) Inexpensive picture frames with your letters puffy painted on them (or, if your handwriting leaves something to be desired, you can buy alphabet stickers and use those).
3) Chocolate covered pretzel rods (melt chocolate chips, dip pretzels in and sprinkle on sprinkles in your colors)
4) Glass candy jars w/ letters puffy painted on and filled with candy (inexpensive at craft stores).
I can come up with more if I'm forced to think, but there are a few. Hope they help.
