There are times when quilting, when is it hard to avoid that nasty "Y" seam. I was told I volunteered to teach this at our quilt guild tonight. My memory totally shut this volunteer thing right out because I really hate to sew "Y" seams. I can do it, but it is often accompanied with naughty language. In preparing for tonight, I googled "Y" seams and came up with a couple of you tube videos to watch. I learned from them. The first video was called Rex's Y-seam demo and the second was Quilting tips make the Y seam easier. It really helped me.
The first step in the Y seam process is you join the diamonds together, leaving a quarter inch unsewed where the Y seam is going to be.
It helps if you clip right where the 1/4" seam ends.
Next, you take your square and I start at the opposite end and sew to within a 1/4" from the intersection. I also clip this portion. Next, keeping all other edges free from being caught, sew from the intersection out 1/4". I also like to clip this area as well. The clips allow you to press your seams open to reduce bulk. Wish me luck tonight....
