I used to hate Valentine's Day- too many expectations, too much sadness, too much money, too much period. It really became a Hallmark holiday for me which equals a reason for people to buy stuff so they don't disappoint others.
I now use Hallmark holidays like Valentine's Day to remind myself about love and generosity and kindness. To do something just because, something unexpected- for someone you may not even know. I am a fibre artist. For me that means I hand dye fabric and fibre and knit and felt and spin and obsess about all things fibre. I made some felt hearts- added them to some indigo dyed cotton. It got a bit out of control, I think there are over 100 now. I stiched paper on the back for a note. Now they are hanging out in places where you can find Bad Duck Caramel. It's a just because from me to you.
Do many things or one thing. If you love Valentine's awesome! Go all out. If you hate Valentine's I encourage you to take it back!
