Welcome from WV. I use a machine that has a 1/4 inch guide. If you have other machines or others who are sewing on the same quilt, I always have them double check their 1/4 inch to make sure that all are the same. I try to have them check the 1/4 inch each time they start to sew, just to get in the habit of realizing the importance. Hope this did not confuse you. Always be consistant!! Happy Quilting. :-D
