One day at the school library I found one of the book covers in my bag and I had several books in there as well and I put this together xD keeps them together and they are less likely to get damaged! For the people who may be interested in the books I used for the demonstration are Torment: A fallen novel by Lauren Kate, That Was Then This Is Now by S.E Hinton, and The Haunting Of Derek Stone by Tony Abbott.
First gather your books and book cover.
Carefully put your books in the cover. Note: be very careful with paperback books because you could bend the corners back.
After you put all your books in simply close is and put it in your bag ^^
