To be honest, following the lines on some printable free motion quilting patterns can be a bit tricky at first. The scale is often quite small unless you print them out huge. I’ve found it helps to use a light pad underneath to see the lines better. Tracing over the design with a light fabric pencil before quilting also makes keeping track of where you’re at less nerve-wracking. Sometimes it takes a view tries to get comfortable interpreting the lines. Stick with it – it’ll make sense eventually!
