Sometimes I just have to draw something goofy to break myself out of a rut. When I was a kid I used to draw funny or overly literal illustrations for common sayings (like, a bunch of butterflies chatting at a party - social butterflies), but I decided to just go literal for "Needle in a Haystack"
I did think of another possible illustration for it - have you ever had a Haystack Supper? Around here they serve "haystacks" for fundraisers mostly - it' a bunch of food out in bowls and you pile what you want onto your plate in layers.
We had it at our last office lunch - there were crackers, lettuce, ground beef, nacho cheese, Doritos, pineapple chunks, diced peppers, tomatoes and probably more.
I didn't have all of that mixed together - but other people did.
