Shadow, have you been doing the twice a month blocks already? Some are fairly ambitious and take a lot of time and forethought. If your plan is to only do beginner blocks to fit in the time frame, you may find yourself running out of pattern choices before you run out of weeks.
Can you really commit to maintaining and keeping the program going, or will you disappear when beginner blocks no longer are a challenge for you?
