>> But I did get 7 or 8 fills for my Valentine's card done, which is an amount I'm happy with; this theme wasn't as easy for me. <<

That's still good.

>> I don't think March will work for me, I don't think I could do the theme justice. <<

You could...

* Take a break for the month and work on something else.

* Play a card from a different theme.

* Look at unfinished cards and write fills for them.

* Check the current theme and look for prompts that could be interpreted other ways, then make a card with those.
