Ngatu is the Tongan term for barkcloth — a non-woven textile produced by beating the inner bark of the paper mulberry tree (hiapo, Broussonetia papyrifera) until the cellulose fibers meld into a continuous, parchment-like sheet. The Tongan barkcloth tradition is among the most sophisticated in the Pacific: the bark-preparation and beating process, the koka bleaching system, and the kupesi rubbing-tablet pattern transfer technique all represent technical knowledge systems that require multi-year apprenticeship to master and that produce material documentation value for Patreon audiences. The Pacific Islander diaspora in New Zealand, the United States, and Australia has maintained ngatu production and use for ceremonial contexts — weddings, funerals, royal gifting, kava ceremony decoration — and the Patreon audience among Pacific Islander communities runs at approximately 55 to 65 percent iOS concentration.

Bark preparation, beating mechanics, and sheet joining

Paper mulberry trees are planted and managed in Tonga specifically for ngatu production, with young trees harvested at approximately two to three years of growth when the inner bark has developed sufficient fiber length and density. The bark preparation process begins with harvesting young straight branches, scraping off the rough outer bark with a shell or knife to expose the smooth inner bast (the fibrous inner bark layer that will become the cloth), and soaking the inner bark strips in water for several hours to soften the cellulose fibers. The softened inner bark strips are then beaten on a wooden or stone anvil using the ike (a grooved wooden beater) to thin and widen the strips: the grooves on the beating surface create a ribbed texture during the initial beating stages, and subsequent beating with a smooth face of the ike consolidates the texture. Multiple beating sessions thin the bark strip progressively, widening it three to four times its original width as the cellulose fibers are compressed and spread laterally. Individual beaten strips are joined into larger sheets by overlapping wet strips and beating the overlapped sections: the wet cellulose fibers naturally felt and adhere to each other under the mechanical pressure of beating, producing a seam that, when dry, is nearly invisible and structurally continuous with the surrounding sheet. This joining process is the key to producing the large-format ceremonial ngatu, which can reach lengths of 20 to 50 meters for major royal gifting occasions, assembled from hundreds of individual beaten and joined strip sections. The documentation of the joining technique — the required overlap width, the beating direction at the join, the moisture level needed for adhesion — is practical information unavailable in any published tutorial.

Koka bleaching and kupesi rubbing pattern transfer

The freshly beaten ngatu sheet is greenish-white from the fresh chlorophyll of the inner bark fiber; ceremonial ngatu is typically a warm cream-white achieved through the koka bleaching process. Koka (bleaching) involves laying the joined green ngatu sheets on the ground and exposing them to direct tropical sunlight for several days, re-wetting the sheets regularly to prevent cracking and to continue the photochemical bleaching process. The chlorophyll degrades progressively in UV exposure, and the cellulose fibers whiten to the characteristic cream-to-white tone of finished ngatu. The bleaching duration varies with sunlight intensity and the desired final tone: a light exposure produces warm cream; extended exposure produces a brighter white. After bleaching and drying, the ngatu is sized with a starch or gum solution to stiffen the surface for pattern application.

The kupesi is a carved wooden rubbing tablet — a flat board with low-relief raised design carved or stitched into its surface — used as a rubbing pattern source in the ngatu decoration process. The dried and sized ngatu sheet is placed over the kupesi, and a pigment-soaked pad (typically a pad of soft bark or coconut fiber saturated with the brown pigment extracted from the koka tree bark, or with charcoal-based black pigment) is rubbed across the surface of the ngatu over the kupesi. The raised design of the kupesi transfers as a rubbed pattern onto the ngatu surface, producing the geometric motif field that characterizes decorated Tongan ngatu. The operator controls the pattern by the position and pressure of the pad, and the pattern repeats by repositioning the kupesi underneath the cloth. Free-hand painted details in brown and black pigments are added after the rubbed base pattern to complete the design vocabulary: geometric repeating fields from the kupesi augmented by free-hand curvilinear and figurative elements applied with a pandanus-leaf pen.

Pacific Islander diaspora and the Apple Tax

The Pacific Islander diaspora for Tongan barkcloth Patreon content is concentrated in Auckland, New Zealand (which has the largest urban Tongan population in the world outside Tonga itself, approximately 60,000–70,000 Tongan-origin residents), in Utah (Provo and Salt Lake City area, with a substantial Tongan-American community associated with the Church of Jesus Christ of Latter-day Saints), in California (Los Angeles area and Bay Area), and in Hawaii. In Australia, Tongan diaspora communities are concentrated in Sydney and Brisbane. The iOS concentration for this diaspora is estimated at 55 to 65 percent, reflecting the moderate iPhone adoption rates in New Zealand (approximately 55–65 percent) and the Pacific Islander-American community’s median-income demographic. At $200 per month with 58 percent iOS, Apple’s 30 percent commission from November 2026 is $34.80/month ($417.60/year). At $350 per month with 60 percent iOS, the commission is $63/month ($756/year). At $500 per month with 62 percent iOS, the commission is $93/month ($1,116/year). Web-only subscription routing via KeepTier eliminates this commission entirely at $9/month per creator.
