Curlz Regular Fill/FlossOutline comes in 2", 3", 4" & 5" heights. Set height is based on the capaital "A" and all other characters are proportional to that. Includes uppercase letters, lowercase letters, numbers and four punctuations. Some characters in the 4" & 5" sets exceed 4x4 hoop limitations. Two-color designs require proper garment stabilization and thread tension to minimize fabric pull (stretching, flaring or puckering) to ensure that the second color aligns properly.
