I'm with others in not understanding what an "Officer's Challenge" is or why it would be some time comsuming. Our guild has a challenge but everyone who wants to does it. It isn't all that time consuming for the committee during the year but there is extra time needed early on in the planning the theme and at the end when the entries are shown. This year ours is a two color challenge. The participant picks out two colors and can use different gradations of those colors and makes something that is lap size or smaller.
