AHHHHHHHHHH, that usually happens to me, but recently I was asked to make a Boston Red Socks quilt for a (1) year old. I am a Yankee Fan! Well, my first instinct was to go out and buy baseball fabric, my local quilt shop rolled her eyes and said they didn't have it. That was my challange. I went to my rack and pulled every white and red fabric I owned and made baseballs using the feather stitch as the stitching on the ball. The quilt is fabulous, I am taking it on a lecture and a curved piecing class sample I am teaching and then I am giving it to the 18 month old for a gift in february.
In other words, don't fall into the trap like I almost did. Think beyond the box, I know you have the creative juices and everything you need.
