"It's picture books."
A distinct sniff went over the assembly, only kept in check by a desire to be polite.
"There can't be anything awfully new about picture books," said Tom.
"Especially cloth picture books. You and Helen have been cutting out cambric for cloth picture books," accused Ethel Brown.
"Della has been making some variations, though." Helen came to Della's rescue. "She's made some with the leaves all one color, pink or blue; and here's another one with a variety—two pages light pink, and the next two pages pale green."
Ethel Brown cast a more interested eye toward the picture book display.
"How do you sew them together?" she asked.
"You can do it on the machine and let it go at that. In fact, that's the best plan even if you go on to add some decoration of feather-stitching or cat-stitching. The machine stitching makes it firmer."
"Is there an interlining?"
"I tried them with and without an interlining. I don't think an interlining is necessary. The two thicknesses of cambric are all you need."
