her pencil case breaks due to being over crammed with essential things! Does she head to the shops with her purse- not when she's being frugal. She head to her bedroom where she keeps her stash and the sewing machine. Within 5 minutes she has carried the sewing machine down to the table, made a pencil case and put the sewing machine away again!
Take a scrap of material and a zip from the stash.
And here it is- a perfect pencil case with plenty of space.
