Heat oven to 350°F. For each cookie, place 2 pretzels with flat sides touching on ungreased large cookie sheets, 3 inches apart. Cut dough into 48 (1/4-inch) slices. (If dough cracks, allow to sit at room temperature a few minutes.) To make angel body, fold in opposite sides at top of each slice to make triangular-shaped body; place each slice on top of 2 pretzels, so double rounds of pretzels form angel wings at each side. Press lightly into pretzels. Using reserved dough from plastic bag, roll 1/2 teaspoon dough into ball; place on top for head of each angel. Press 2 sliced almonds into dough to make song book. Repeat to make 48 cookies.
