@marvellous.mama: These Russian triangle letter folds are SO cool! Write a note and fold it closed- no need for an envelope! These don’t even really need a sticker to seal them but it’s worth it if you’ll be putting your letter in the mail. 💌 📬 Use an A4 sheet of paper of your choosing and get folding! NO glue or cutting needed. You can go for a smaller sized note if you like. You’ll need to stick to the same measurement ratios as an A4 sheet of paper. Enjoy! #origami #paper #papercraft #handmade #homemade #gift #notes #letter #letterfold #letterlocking
