HOW TO CHECK YOUR SEAM ALLOWANCE
If you're new to quilting, I recommend that you purchase a seam gauge. You can use it to find the exact setting on your machine to give you a scant 1/4" seam allowance.
Do not move your iron side to side as you press. Instead, pick it up and move it as you move along the seam. Moving the iron from side to side can distort your fabric.
WHAT IS A DESIGN WALL?
A design wall is just a blank space to used to lay out quilt blocks before they are sewn together. You can purchase inexpensive vinyl design walls online.
