This section is from the book "Busy Hands: Construction Work For Children", by Isabelle F. Bowker. Also available from Amazon: Busy Hands: Construction Work for Children.
Material: Medium-weight colored paper 6 in. x 12 in.; five pictures; scissors and paste.
Fold the paper by placing the two short edges together.
Round each corner, as in Fig. 2, and scallop the cut edges of each page. Care should be taken to leave the paper double at r-s, for a hinge.
Turn back the under page.
Parallel to each rounded corner, cut a slit half an inch from the edge. (m-s, Fig. 2.) Scallop or point the edges of the half-inch bands thus formed. (A pretty trimming is made by cutting small slits and turning back every other section, as in
Fig. 3)
In the center of the upper page of the valentine, cut two slits crossing each other, (x-y, and c-d.) Turn back the triangular pieces, and point the edges. (0, Fig. 2.)
Bend back the circular pieces inside the half-inch bands and paste them to the points of these triangular pieces.
Paste a picture upon the under page of the valentine, beneath the center opening.
Paste four pictures upon the under page of the valentine, beneath the circular openings.
In the four spaces around the pictures write: "To My Valentine"; "With Kind Regards"; "Best Wishes"; "Think of Me."
Write these little mottoes in such a way that they cannot be seen through the openings in the upper page of the valentine.
