1) ok first of all take 4 sheets of A4 card... i use white as it clean and neat in your photographs but theres nothing stopping you using any other colour to match your blog background - just keep it plain and simple. for the tutorial ive used a pink cellotape just so it shows up and you can see it.
2) take 2 of the sheets and tape them from top to bottom down the longest length.
5) now give all the seams a good fold and a crease along where you have taped
6) your backdrop is now finished!! just turn it so the none taped side is facing you and the untaped pieces are at the bottom. overlap these 2 pieces as so and your backdrop will stand up on its own
