This is cute. Do they have a blank book? I thought about using gift bags and do the same thing but put things in it that my grand babies might like.
There is one page with little embroidery on it, inside cover page. You could edit the page by putting something over the design, then when embroidering, just skip the original design and start on your own.
She did have a blank, larger version book, I used on the Farm alpha, on her Yahoo account. I'll take a peek and add it to this section.
