Oh, and.... I bought some more writing paper!
These sets were buy one get one free... normally £1.99 each in the shop, though occasionally they have 2 for £2 offers too.
I also looked in a charity shop and found this luxury keepsake box portfolio..
with 20 writing sheets (A5), 20 envelopes and 10 blank cards. Not bad for £1 and good to support this charity.
