I have made similar ones using wired silk ribbon, or silk fabric cut into strips. It works well and the roses are beautiful. Fabric cut on bias looks especially good and an ombre looks almost real. Didn't use tape or artifical leaves. Just sewed. Can use bias binding to wrap stem if desired.
I didn't have any problem reading the instructions. All I did was click the magnifier on my Adobe Reader tool bar until it brought it to the size where I could read it. Nice project.
You could use a rip-stop nylon or other light weight, make it self lined, and zig-zag a light weight length of wire to give it the appearance of something more in tune with the roses, or do as they suggest as it will take far less time, and they are already wired. If taking apart the silk flowers, use the petals for other craft or sewing projects.
Why take apart a purchased rose to make a fabric rose. The fabric rose could be lovely when it coordinates with an outfit but don't use the parts from a cheap purchase. wire, tape and ribbons could make the stem and leaves.
easy to make and very pretty
