My quilt buddy says I have an eye for picking coordinating fabrics. But I do use the colored dots on the selvedge to help pick out fabrics and I also don't rush. When I decide on my focus fabric, I then choose my others but I don't rush. I will sometimes take days to decide. I put the focus fabric down, start placing other fabrics around it, stand back and check it out. I will sometimes take pictures with my phone, walk away, come back at a later time with fresh eyes and do what needs to be done - either keep what I chose or change something. It's different when you only have 2 or 3 fabrics in a quilt but when you have to have more then that you really need to take your time. I generally shop from my stash when making a quilt, but if you don't have a stash you can buy your focus fabric from a companies particular line and all the coordinating fabrics they make to go with it. Can't wait to see some of your projects.
