These Holiday Trees are knit in the round using double pointed needles and fitted around a styrofoam cone. There are 3 sizes of cones needed. 4.25”, 7” and 11.5”. Decreases give the look of a cable going up the trees. The pattern has very detailed and easy to read instructions for each size tree and also includes instructions for adding beads. If adding beads, I used about 125 size 6 clear silver lined beads for all three trees.
