Birgit Palma and Daniel Triendl are the Austrian illustration duo who express visual experimentation through bold colors and geometric shapes. The artists have enjoyed working online together remotely from Barcelona to Vienna since 1985.
What you'll need
Open the library you created earlier (Window > Libraries) and drag the Brush 1 texture to the selected frame.
Double-click the texture image inside the frame and use Control+T (Windows), or Command+T (macOS), to change its size and position. Or select the texture thumbnail in the Layers panel and use Control+T or Command+T.
Use the Pen tool to make any shape into a frame. Trace the part of the letter you want to use as its own frame. When your selection is complete, right-click on the new shape layer in the Layers panel and choose Convert to Frame. Then, fill it with the texture you want from the Libraries panel.
