This listing is for a downloadable letter-sized 8½ x 11 single-page PDF of a coloring page, at 300 DPI and suitable for printing.
'Hercules' is a no-frills knotwork design with lots of straight lines and easily-defined loops of cord. I like using it for rainbows and color gradients. I find it just challenging enough to keep me from losing focus, without distracting me from audiobooks or podcasts. Colorers who find repetitive tasks soothing will particularly enjoy this page. The simple nature of the design makes it ideal for printing multiple times to try different color schemes.
This design can be printed on any letter-sized page that you'd like, and shouldn't even need to be resized (though it can be if you prefer wider margins). Certain PDF readers and printer settings may cause the lines to have slight amounts of aliasing; I've have the best luck using Adobe Acrobat, but your mileage may very. Print onto regular copy paper to color with pencils, or onto cardstock to color with fine-point markers.
My knotwork coloring pages are intricate, tiny, and very advanced! That makes them unsuitable for colorers with poor fine motor control or any disabilities of the hand that could cause pain. I don't want anyone to hurt themselves trying to color these pages in! Take plenty of breaks, stretch your hands, and be careful of your posture.
This coloring page is for personal use only. There are no watermarks, nor is there any text to distract from the knotwork. This means that there is no DRM or protection of any kind on this product! This is entirely on the honor system. I keep my prices low in the hopes that everyone who wants one can buy a copy of this coloring page.
You may print this file as many times as you like, and share printouts with whoever you'd like. Just don't try to sell the finished colored pages, or present the knotwork pattern as your own. If you post a picture of your finished creation online, I'd love it if you tagged @KittyUnpretty or linked back to this listing (or both).
