I do not have an embroidery machine so I cannot give you specific sizes. But I am wondering if you could ask your dealer for advice? Perhaps there is a conversion chart you could use? It seems to me that you should have dealer support...the Designer SE is a great machine and I am sure the dealer will want you to get the absolute most benefit from it. One of these days I will have either that machine or a Diamond...I am starting to see the light at the end of the college tuition tunnel!
