Mini Block Font comes in 2/10", 3/10", 4/10", 5/10" and 6/10" hieghts. All sizes use satin stitching and include uppercase, lowercase, numbers and four punctuations. These are very small letters with very short stitches on the smallest sizes. For best stitch quality the following are reccomended: Use on medium wieght non-stretchy fabric; use an iron-on/tear-away type stabilizer; use the smallest hoop available for greater project stabilization; decrease upper thread tension to prevent "pull"; test stitch first to determine any adjustments for fabric or stabilzer used. The stitch sample below was stitched out on a Janome 300E on a medium wieght Cotton Twill with Iron-on/tear-away stabilizer.
