Description of book with helpful details: 2 girls (friends) playing dress up, hanging clothes on a line, and maybe a tea party. Book had pen and ink illustrations I believe. I remember a drawing of one of the girls wearing high heels that were of course too big for her. I checked this book out of my grammar school library many times, probably in the late 60’s.
The Sign on Rosie’s Door by Maurice Sendak? I remember the clothes hanging up and the too-big high heels.
No, but thank you.
Betsy-Tacy by Maud Hart Lovelace?
None of the above, but thank you!
Let’s Play House?
Possibly The Magic Friend Maker?
One of the Catherine Woolley books possibly.
Maybe Cathy’s Little Sister? I think it has a very similar sounding illustrations and Chris had a party during her playdate after they played dress up.
