I am making the 4 quilt in my life so I am still learning, alot. This quilt I am working on has sashing and this is my first experience. My quilt blocks are 15"x15" and are placed 4 across and 5 down. I have enough fabric to do all this but I will have to piece the horizontal sashing pieces.. First question is that acceptable to piece the sashing and second question do I alternate the seams or keep them all in the same spot. This pattern did not call for sashing but I am using Marmalade print fabric and the pattern is called Lucky Stars. I thought there was just too much going on between the blocks without the sashing . Sorry I don't have any pics but hope to be able to post my finished produce. Thank you for any help.
