What is the best technique to make them look really good.
The way i make them is ok, but i am sure there are better ways.
Please do not hold back with suggestions.
do you mean the actual bow, or the colour? i havent tried making proper bows yet, but i would say that lustre dusts are the way to go for the colour!
For the color - using Americolor's gold and then brushing it with gold luster dust. For making ribbons that are all the same size - I think Global Sugar Arts has a "ribbon wheel" that will help you cut them all the same size.
I have just started using the Gold airbrush paint from GlobalSugarArt. I have actually used it two ways, one by brushing it on, which takes several coats, and two with the airbrush wich works very well.
I used to use the Gold Luster Dust, mix with alcohol, and paint it on, but I really like the airbrush paint.
