Hate it if you have written or typed a perfect letter and then when you fold it to put in the envelope you mess up and it looks bad? Well this is the perfect solution!
Step 1: Materials
*Paper (any size)
Step 2: Roll
Roll the letter twice so that the two ends meet. See the picture for clarification.
Step 3: Mark
Make a mark there.
Step 4: UnRoll and Fold
Unroll and fold the paper to the mark with the bigger side facing you.
Step 5: Fold Again
Finish folding. Done, you have folded a letter perfectly!
