Curlz Bold Fill/SatinOutline comes in 2.5", 3.5", 4.5" & 5.5" heights. Set height is based on the capital "A" with all other chracters proportional to that. Features fill stitch letters in first color with Satin Overcast Outline in second color. Purchase includes all sizes in uppercase letters, lowercase letters, numbers and four punctuations. Some characters in the 3.5" set with ascenders and descenders exceed 4x4 hoop limitations and some in the 4.5" and 5.5" set exceed 5x7 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.
