The Tangles of Kells card pack features 40 cards with tangles/patterns from my book, The Tangles of Kells. The back of each card has steps (instructions) for a tangle and the front has a sample piece of art using that tangle. The cards come in a clear, two-piece box designed to store and protect the cards. Each card is 2.5x3.5" These cards play well with all my other card packs.
