Impervious Satin/SatinFill Font comes in 1", 2", 3", 4" and 5" heights. The 1" and 2" height sets are finished in standard satin stitch; the 3", 4" and 5" height sets are finished in SatinFill. Set height is based on the capital "A" and other characters are sized proportionally to that. Each size includes uppercase letters, lowercase letters and numbers. Most of the letters in the 4" set and all of the letters in the 5" set require larger than the standard 4x4 hoop. This font is intentionally designed with some crooked and uneven lines which gives it it's playfull character.
