Hello friend! I saw your yarn store map and it's sadly devoid of stores in Argentina, but worry not! I am here to fix that. In Ciudad Autónoma de Buenos Aires (Province of Buenos Aires), you will find about 2-3 ENTIRE BLOCKS dedicated to yarn shops. How awesome is that? Main highlights are Moussa Lanas, on Raúl Scalabrini Ortiz 973, and Hilados Arpa, on Raúl Scalabrini Ortiz 837. Also of note: Cencherle Fábrica de Lanas, on Raúl Scalabrini Ortiz 1001, Helou Hilados, on Raúl Scalabrini Ortiz 1027, Nube Hilados, on Raúl Scalabrini Ortiz 999, Lanas Naturales, on Raúl Scalabrini Ortiz 856, and Yanabey Lanas on Raúl Scalabrini Ortiz 1019. Shoutout to Almacén Litoral for online shopping. There's also Tienda Luno on Av. Nazca 1092, they have some great stuff, though I've never been to the physical store myself. There's.... a LOT more. But basically if you walk down Scalabrini Ortiz 800-1000 you'll just find store after store after store after store, a lot of which are manufacturers and have their own blends and colors and stuff. It's wonderful =D
