It doesn't happen often, but if there is ever a K-9 block, I use dog (canine) fabric.
If you have space for a design wall, I think this would help you a lot. When I use the design wall, I put the squares RST together and mark the seam with a clip. Without the design wall, I do the same as IceBlossom. But I also mark the top with an arrow. Even when I label I have been know to sew it upside down.
Happy sewing!
