The first thing we start with is from sheets of cardboard we need to make the bases of the envelopes. We make each one 20*28.5 cm in size. The pieces of cardboard that remain are made into lace hole punches and will later be useful for decoration.

We divide all three sheets into three parts and fold the blanks. One envelope will be horizontal and two vertical.

We cut six strips of polka dot ribbons, burn the edges and glue them to the bases (envelope ties).

Now from sheets of scrap paper we cut out three rectangles of 9.2 * 19.7 cm for two envelopes, and for the third 9 * 20 cm and 8 * 20 cm. We make cuts in vertical envelopes, and cut scrap blanks accordingly.

We will decorate the remaining rectangles (front parts). We tint the edges of pictures and inscriptions.

We use a glue gun to decorate our envelopes with various beauties. Tie it with bows and you're done! The result was such delicate and bright congratulatory envelopes. Thank you for your attention!
