The Shire did not produce paper, making it an expensive commodity.
Of course, Bilbo Baggins could afford it but packages from Rivendell were always welcome. Sometimes they came with the carter, via Bree, but on other mornings he would find a carefully wrapped package on the doorstep; perhaps left by some passing traveller to the Havens. It seemed Loremaster Elrond remembered a stray comment, in which Burglar Bilbo declared his love of writing.
Now, as Bilbo sat in his study, he heard Frodo in the kitchen, carefully slicing the smooth, creamy sheets into a size more suited to hobbit fingers.
