Decided to share a card which was inspired by this month's challenge. Did not enter into the contest as it does not meet all of the criteria.  
 
Inspired by the January 2016 "Get Back to Nature" challenge theme. Doreen's phrase "products of the earth" really grabbed my creative side.
 
The hardest part of this design was trying to get a little critter integrated into it - which I decided to eliminate. The building blocks of the earth are hazardous to little creatures, no matter what I tried volcanoes and creatures don't exactly go together. So, with the Valentine's Day holiday close I decided to blend the holiday and nature together. Not exactly directly related to ‘Getting Back to Nature’, but I think it flows (pun intended).

Hope this inspires some more ideas for "products of the earth". Good theme, Doreen!
