Warne received and considered the three tales. Potter wrote to him that the cat tale would be the easiest to put together from her existing sketches but preferred to develop the mouse tale. She alerted Warne that she was spending a week with a cousin at Melford Hall and would run the three tales past the children in the house. Warne favoured the mouse tale – perhaps because he was constructing a doll's house in his basement workshop for his niece Winifred Warne – but for the moment, he delayed making a decision and turned his attention to the size of the second book for 1904 because Potter was complaining about being "cramped" with small drawings and was tempted to put more in them than they could hold. Warne suggested a 215 mm x 150 mm format similar to L. Leslie Brooke's recently published "Johnny Crow's Garden", but, in the end, Potter opted for the mouse tale in a small format, instinctively aware the format would be more appropriate for a mouse tale and indicating it would be difficult to spread the mice over a large page. Before a final decision was made, Warne fashioned a large format dummy book called "The Tale of the Doll's House and Hunca Munca" with pictures and text snipped from "The Tailor" to give Potter a general impression of how a large format product would appear, but Potter remained adamant and the small format and the title "The Tale of Two Bad Mice" were finally chosen.
