One ounce may not sound like a lot but these crystals, mixed with water, make a LOT of ink. You won't use this up for a while!

Walnut ink is such a versatile product and the rich brown colour is so gorgeous everybody should have it in their studio. You can make it up in different strengths and use it to age paper and tags, spray it on for speckles, dip tags and papers in it to dye the edges, sprinkle crystals onto your paper and mist with water, etc. etc, etc.
