Two silk ribbon spiderweb roses, complete with leaves and pearl buttons. This is a nice treatment for a smallish patch. There are several tutorials on the web for the spiderweb silk ribbon rose and this is very easy to do.
The next example is a flowing vine. The vine is made with regular floss, leaves are silk ribbon. Lots of little beads to add some sparkle. This is a good treatment for a long, skinny type area. Lightly sketch the vine with a chalk pencil or disappearing marker. Remember not to use an iron when you have used one of these markers, as heat can sometimes set the ink and it will not come out. Again, if some of your patches are made of fabrics other then cotton, be sure and test the markers on the seam allowance.
