Press the child's finger onto a washable ink pad and press the inked finger vertically oriented onto a piece of paper toward the top left corner.
Press the finger onto the paper, vertically, directly underneath the first fingerprint four more times, creating a straight line of fingerprints as in the straight line beginning the letter "K." Return the finger to the ink pad when the fingerprints begin to get light in color.
Ink the finger again and press it onto the paper to the right side of the fingerprint line previously created, at an upward and right facing 45-degree angle. Repeat the fingerprints three more times to create a fingerprint line that is 45-degrees and pointing toward the top edge of the paper.
Return the finger to the ink pad and press it onto the paper just under the upward facing 45-degree angle but facing down and to the right side of the paper. Continue with that line until the end is even with the bottom end of the straight line to its left to complete the letter "K."
Repeat the entire process to create other letters using fingerprints and when creating letters with rounded lines, alter the angle of the finger before pressing it onto the paper. For example, to transform the previous letter "K" instructions to the letter "R," instead of making the upward facing 45-degree angle line, begin again at the top of the straight line fingerprinting a straight horizontal line. After two fingerprints, turn the finger slightly downward with each print.
