I use flashcards everyday in my classroom. They're practical, useful, and convenient. 

I've made DIY alphabet flashcards before, but today's flashcards are comparable to Hefty Bags. Perhaps it's because I accidentally bought the strongest card stock at Michael's which is good because you don't need to print these flashcards. All you need is heavy-duty card stock and stickers. Here's what we did: 

 MATERIALS: Seven sheets of 110lb card stock, scissors, and stickers (which I purchased from Target). 

First, cut the card stock in fourths. You'll need 26 cards. Next, carefully place the stickers onto the cards. 

TADA! Instant, DURABLE flashcards. Enjoy!
