Another thing to consider while deciding on your tattoo sleeves is whether you’ll go with color or not. Sleeve tattoos using only black and grey can look amazing, but there’s nothing more eye-catching and vibrant than an arm full of color. If you do go with color, it’s vital that you plan your tattoo beforehand so you don’t end up with a combination of colors down the road that don’t look too great together. Also keep in mind that a colored sleeve tattoo will require more time and money.
Some tribal cultures traditionally created tattoos by cutting designs into the skin and rubbing the resulting wound with ink, ashes or other agents; some cultures continue this practice, which may be an adjunct to scarification. Some cultures create tattooed marks by hand-tapping the ink into the skin using sharpened sticks or animal bones (made into needles) with clay formed disks or, in modern times, actual needles.
But other than that possible health benefit, tattoos are just downright awesome, especially ones that cover a lot of skin like a sleeve does. It provides the most personal and artistic expression, just due to its massive size. Plus, a tattoo sleeve takes multiple tattoo sessions, so there is plenty of time to get used to and fall in love with a new design.
Tattoos were probably also used in ancient medicine as part of the treatment of the patient. In 1898, Daniel Fouquet, a medical doctor, wrote an article on “medical tattooing” practices in Ancient Egypt, in which he describes the tattooed markings on the female mummies found at the Deir el-Bahari site. He speculated that the tattoos and other scarifications observed on the bodies may have served a medicinal or therapeutic purpose: "The examination of these scars, some white, others blue, leaves in no doubt that they are not, in essence, ornament, but an established treatment for a condition of the pelvis, very probably chronic pelvic peritonitis."
Protection papers were used by American sailors to prevent themselves from being taken off American ships and impressed into the Royal Navy. These were simple documents that described the sailor as being an American sailor. Many of the protection certificates were so general, and it was so easy to abuse the system, that many impressment officers of the Royal Navy paid no attention to them. "In applying for a duplicate Seaman's Protection Certificate in 1817, James Francis stated that he 'had a protection granted him by the Collector of this Port on or about 12 March 1806 which was torn up and destroyed by a British Captain when at sea.'"  One way of making them more specific was to describe a tattoo, which is highly personal, and thus use that description to identify the seaman. As a result, many of the later certificates carried information about tattoos and scars, as well as other specific information. This also perhaps led to an increase and proliferation of tattoos among American seamen. "Frequently their 'protection papers' made reference to tattoos, clear evidence that individual was a seafaring man; rarely did members of the general public adorn themselves with tattoos."
"If the tattoo has small, tight intricate details, they will be lost with time as the cells change and move," Gehrlich says. "When the design is larger, there is more room for displacement and allows the design to still be readable." As your skin ages, your tattoo will change. Getting a larger design may help you prepare for the way it will look later on.
These instruments are also remarkably similar to much later tattooing implements used in 19th-century Egypt. The English writer William Lane (1801-1876) observed, "the operation is performed with several needles (generally seven) tied together: with these the skin is pricked in a desired pattern: some smoke black (of wood or oil), mixed with milk from the breast of a woman, is then rubbed in.... It is generally performed at the age of about 5 or 6 years, and by gipsy-women.”
