Hi Cheri, I'm cutting and pasting the answer I gave you where you posted your question under Season 2: Episode 2 under the Introduction to Sample One. Maybe it's easier for you to find here..... The only other thing you need to take into account is how wide in the reed your item will be so you can first find the centre and then, from there find your right side starting point in your reed. The math is simple if you have a 12 dent reed and you want to sett at 24 epi. With other setts and reeds - it's easier to check on the chart that Jane provides.
Hi Cheri, you don’t need to do the math - you’ll find it all on Jane’s Reed Substitution Chart. If you are using a 12 dent reed and you are opening your sett up from 18 to 15 epi, you look at the column for your reed and find the 15 epi on the list and use the sleying listed in the far left column of the chart.
