For this Eid I made some Eid Cards. I have a small tutorial of one of the cards that I made for someone.
Glittery Alphabet Stickers
Coloured A4 Card
Optional: stickers and pens
Fold the A4 Card in half.
Apply the stickers carefully spelling out the words Eid Mubarak
If you wish to add further decoration you could add other small stickers or use a pen and draw some nice designs in the corner or anywhere on the card.
