Why are Modello patterns generally only used for “low relief” embossing?
The term “low relief embossing” implies that your textural material will be applied thinly. When embossing with a traditional stencil, the stencil is pulled away immediately after the embossing technique is applied. A Modello pattern must be left in place until the embossing medium has completely dried. Otherwise you run a great risk of ruining your embossed “print” while trying to peel out the vinyl material. Another issue to be aware of when using a Modello pattern is that your embossing material must be applied thinly enough so that you can SEE the Modello pattern to remove it. In some cases, your Modello pattern will have a continuous connection, allowing you to remove it in one piece. This would allow you to apply the embossing a little thicker. Most Modello patterns have many small “inside” pieces to them, however. Think of these as “islands”. If you bury them into obscurity, they may be impossible to find later.
