Making your own silk floral cascading bouquet is a cost-effective and elegant choice. A cascading bouquet flows from the hand in a teardrop shape. It is the most elaborate and formal bouquet style. The most important step in making your own bouquet is to find a plastic bouquet holder with a slanted handle, not a straight one. Straight handles are made for round bouquets and slanted handles are made for cascading bouquets.
Arrange the ivy around the outside of the bouquet foam, cutting the stems so that no piece falls more than 5 inches from the holder. Lightly fill in the main body of the bouquet with ivy that falls no more than 4 inches.
Cut a single piece of ivy so that it will fall 9 inches from the holder. Place the long piece of ivy at the middle-bottom of the bouquet. Cut two pieces of ivy so that they will fall 8 inches from the holder. Place the pieces of ivy on each side of the long piece, leaving a 1-inch gap between each strand.
Cut two pieces of fern so that they will fall 7 inches from the holder. Place a piece of fern on each side of the 8-inch-long ivy, leaving a 1-inch gap between each strand. Lightly fill the main body of the bouquet with three to five more pieces of fern that hang no more than 5 inches from the bouquet foam.
Cluster three large, silk roses in the middle of the bouquet. Use five more large roses to help fill in the general bouquet shape. Make sure the roses fall no more than 5 inches from the bouquet holder.
Cut three large roses so that they will fall 5, 6 and 7 inches from the bouquet, respectively. Place the long roses toward the middle-bottom of the bouquet and bend the stems so that the roses hang down in a subtle style.
Cut two small roses so they will fall 6 and 7 inches from the bouquet, respectively. Arrange roses toward the middle-bottom of the bouquet and bend the stems so that the roses hang down. Arrange five to nine of the small roses to fill out the bouquet as needed.
Cut some ribbon and wind it up and around the plastic bouquet handle. Tie the ribbon in a small bow at the rim so it is hidden by the bouquet.
Depending on the exact type of bouquet holder and silk flowers you're using, you may have difficulties keeping the stems in the holder. To solve the problem, dab some craft glue to the bottom of each stem before sticking it into the foam holder. The glue will dry and keep the stem in place.
