As one who has pushed the deadline a couple of times, here are my feelings.
Shorten the build period to three, or at most, four months. If there is a definite deadline most everybody (including myself) will make it happen. As mentioned by others, bow building is then kept in the bow building season. Personally, I'd prefer it to start in December and be due March 1st.
I really like the idea that everybody ships at the same time. It creates a concrete deadline.
The current Trade thread is nice, but I quit following it after the end of July; figured if the builder was not interested enough in getting their bow done, I wasn't interested looking at it. Unfortunately, the recipient is the one who doesn't have the enjoyment of sharing.
Personally, I have received nice bows every year. However, I do not care what I receive, for me it's mostly about building something out of my usual comfort zone that fits the recipient.
Regardless, I will be in the trade next year, whatever the of the rules.
Kelly, I will send you a pm.
