Elongated Honeycombs are honeycombs that have been stretched! They still have the right angle at each end like a honeycomb, but their long side is twice the length of their short side. They are measured along the long side.
All of our acrylic templates have a 3/8" seam allowance and holes for marking fabric. They come with a protective polyethylene sticker to avoid scratching and breakages during production and transit. Simply peel off before use. Wipe with a wet cloth if any sticker remains.
