Fun toddler activities?

Ashley • Mommy to a sweet little man!
Hey guys! I'm a big Pinterest gal, of course. However the toddler activities I seem to try with my 15 month old always seem to go wrong (sometimes pretty badly wrong haha!). Any personal favorites that you guys have tried and loved? My son is bored being inside this winter and has no interest in his toys. We also don't really have a ton of cash to go out and buy arts and crafts at the moment. Thanks for the advice!
