I find that many of us Slowly users tend to be both Cat and Book lovers.
All the Cat-themed stamp issues did well - my favourite being the gorgeous '
Purrfect Holidays
' set, still available via the Time Machine.
The suggestion would be for
a set of stamps presenting both of those passions
. I follow a great account on Twitter called 'Reading with Cats' and delight on the imagery she posts and shares on this theme. https://twitter.com/bookcatbliss
Some examples included here, art work taken from her account.
Thank you, and please comment if you have any suggestions or ideas on this!
