watermark


In the making of paper, a translucent design impressed on it when still moist by a metal pattern, and visible when the paper is held before light. In digital imaging, bits altered within an image to create a pattern which indicates proof of ownership; so that unauthorized use of a watermarked image can then be traced.


ukiyo-e

Japanese for 'pictures of the floating world'. Ukiyo-e were popular in the seventeenth to nineteenth-centuries, and depicted kabuki actors, landscapes, and folk tales.

undercut

Carving to create an overhang; a recess or awkward angle in the surface or form of a three-dimensional object which would prevent easy removal of a cast from a mold. Molds should be designed to eliminate this problem. Ways to cast objects with overhangs include using piece molds and waste molds.

underdrawing

underpainting

The layer or layers of color on a painting surface applied before the overpainting, or final coat. There are many types of underpainting. One type is an all-over tinting of a white ground. Another is a blocked out image in diluted oil colors that serves as a guide for the painter while developing the composition and color effects.

A great deal if you are on a budget for arts and crafts! I don't professionally craft but do so often, so this is right up my alley!

Great Product. Holds my completed diamond paintings nicely!

These paints add an effect to your clear glass that mimics a stained glass effect. They are more "see through" and not opaque. They are very thin and take more paint for coverage than other glass paints but I really like the effect they give. The colors are beautiful and very different from other paints I have tried.
