F.A.Q.
Do I need to do all 7 days in order to participate?
• Not at all! Feel free to only do the days you're most interested in.
Do I have to do both prompts for each day?
• Nope! You can if you’d like (whether that’s combining both into one entry or doing two separate entries), but you only need to do one for each day you participate. Two prompts are provided simply to give more room for creativity!
When can I start working on my entries?
• Right now! It's common to have most, if not all, of your entries done before the ship week begins. Please do whatever is easiest for you!
My entry hasn’t been shared yet!
• Please be sure to tag @heromariweek on each post! If 24 hours have passed and your entry still hasn't been shared, please re-tag @heromariweek or @zipsunz in the comment section to bump it in the notifications tab.
