It's Secret Sister time!

Our playgroup is doing a SS for Valentine's Day (and possibly all of Feb). We have a very minute dollar limit ($5) and I'm so unimaginative. What am I going to do for the next 2 weeks much less 4 if we keep going?? I'm used to a much bigger budget ($20). LOL My scatterbrained pregnant self is at a loss right now... I'll think of something though!
