This set comes with Left and Right upper case letters in 6" size.
The individual letters will fit in a 5x7 hoop, but to do a 2 letter monogram, you will need a larger hoop. None of the letters will work in a 4x4 hoop.
The following formats are included in the download: PES, DST, EXP, HUS, JEF, VP3, VIP, and XXX.
Also includes .BX format that works with Embrilliance Essentials, AlphaTricks, and Designers Gallery EmbroideryWorks that will allow you to use the letters as a keyboard font.
