Summarize this article:

Start with about 5 cuts of each color and cut more as needed. Make sure that every cone has the shiny side of the ribbon facing outward. Staple the ribbon on it's fold to hold the cone shape. Position the cones so that the points are pointing away from the backer, staple base of the cone. For the first layer, use the same color cones and leave about a quarter to a half inch of space between each cone. Continue to staple the cones until the entire edge of the backer is filled with cones. It should look like a drawing of a sun or a flower.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/ba\/Make-Homecoming-Mums-Step-6Bullet1.jpg\/v4-460px-Make-Homecoming-Mums-Step-6Bullet1.jpg","bigUrl":"\/images\/thumb\/b\/ba\/Make-Homecoming-Mums-Step-6Bullet1.jpg\/aid466916-v4-728px-Make-Homecoming-Mums-Step-6Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} Remember to staple  the base of the cone on the backside of the backer. The flower can be either real or fake, but most used are generally fake to prevent wilting. Set the mum aside and allow the glue to dry for several minutes. If you want to make a double mum, simply use a double backer with two holes instead of one and attach two flowers using a glue gun. Again, start with about 5 strips of each and then cut as many  as needed to create a full-looking mum.  Be sure to use a hot glue gun to fasten charms and other heavier objects to the ribbons. To make a military braid, begin by stapling the ends of two different colored ribbons together at a right angle.  Next, fold a colored ribbon towards you, forming a loop as long as the ribbon is wide and staple the ribbons together where they intersect. Take a loop of your second ribbon and bring it through the original loop of the first ribbon. Continue to bring a loop of the first ribbon through the second ribbon and pull the second ribbon tight around the first ribbon. Remember to alternate ribbon colors as you continue to do this until you reach the end of the ribbons. You will use your middle backer with the streamers for this step.  Cut several pieces of curling ribbon each 36 inches (91.4 cm) long and tie a small bell to the end of each piece. Attach to the middle backer using hot glue. Staple the loop to the top center of the third, unused backer. This will serve as the base for your safety pin. Glue the third backer with the safety pin loop onto the back of middle backer to cover staple edges and protect clothing from staple snags. Allow the glue to dry. Then simply attach the pin to your clothing.

Summary:
Cut some  4-inch lengths from #3 and #5 ribbon until you have enough to create cones around the entire edge of one cardboard backer. Overlap the pieces and twist both ends in the same direction to form a cone shape. Staple the completed cone-shaped ribbon to the back edges of the cardboard backer. Fill in the spaces between the cones with a second row of cones using the second color of ribbon. Remove the stem from the mum flower. Take the backer of the pointed ribbons and glue the mum to the front middle of the backer using a hot glue gun. Pick up #5 and #9 ribbon in the color of your choice and cut several 48-inch-long strips. Take your 48-inch pieces and fold them in half to create 24-inch streamers. Embellish the lengths of the ribbons with any sort of decorations you desire once your backer looks full of ribbons Some ideas includes writing words out in glitter glue, fastening beads, rhinestones, or small plush figurines, and even putting photographs on the ribbons. Make a military braid from your ribbons if desired. Tie on bells using curling ribbon if desired. Take two 5-inch pieces of #5 and #9 ribbon and overlap them several times to form a loop. Complete embellishments to your satisfaction. Glue any central charms on the mum and add any final touches to the piece. To wear your mum, take your large safety pin and thread it through the loop you created on the back backer with the two 5-inch pieces of ribbon. Finished!
