Hello ! Each letter is 10 rows long, so it starts on 1, 11, 21... and ends on 10, 20, 30 etc. You can combine any letter, number and symbol. Letters Q- Z : #173011 Numbers : #173012 Some punctuation and random symbols : #173013 If you're having trouble using it, feel free to PM me 🙂 I can also give you the knot sequence for whatever you want to write so you can input it into the pattern generator
