For making paper roses you take a cardboard and cut petals out of it. There should be three different sizes of petals; the smaller ones for the center and the larger ones for the outer layer of the flowers. The petals should be provided with small stubs so that they can be attached securely to the floral wire. Now, place each cardboard you have shaped on the paper or silk and trace out the outlines. Calculate the number of flowers you would like to make and calculate the number of petals you would like to put in each layer of each flower.
Take floral wire and fix each of the petals securely on the wire by means of a green tape. You can include as many petals as you want and as many layers you would like your flowers to have. For each flower, 14 to 16 petals should be enough with three layers of petals. Use the larger petals as you move towards the exterior.
You can also have leaves cut in the same manner and tape them to the wire. For a better result you can use real rose petals and leaves as models to have the designed shapes of petal or leaves close to original.
If you have chosen paper for making your bouquet then to make your flowers look even more beautiful you can coat the petals with liquid paraffin or you can use a mix and match of two or more different colors of paper or silk for designing the flowers. After you arrange the flowers in the bouquet, you can spray it with a light fragrance and sprinkle it lightly with water to give it the semblance of fresh flowers.
