The First Rule of Bead-A-Long
You need never apologize for bead-a-long. Or bead not-quite-a-long.
Craft guilt is never an option. So you're late. Post it anyway. As long as you don't stiff someone if we ever do decide to do a swap - this is purely about getting a little more excited about your work than you would be on your lonesome and having fun. That's it.
Feel free to sit out a challenge that doesn't do it for you, throw out your own challenge for the following month, take the basic challenge and push it into a different direction.
Beads and fun and productivity, that's it. Yay!
