Just made a paper bag album for someone, using some of my kit bags that my SC papers come in. It makes an album about 12 x 9.I use a range of coordinated papers cut into 6 in strips, then decorate with other pieces and some Washi tape.
Some pages I trim down to a shorter size so that it introduces variety.
I try to make some pages quite plain for journaling. These are a great gift for people, as they can use them however they want! These pages have hidden pockets too which make them more versatile. TFLx
