I use a hoop. It is the only thing that makes it managable for me.
Also, you might try freezer paper for your applique. Cut it to the size you want your finished piece to be, being careful to trace it flipped over (if you want your pattern facing right, trace it facing left, as the paper will be fused to the back of the piece you are appliqueing). Iron it to the back of the fabric being appliqued. Cut out the design, leaving 1/4 inch around the outside edge to turn under. You can glue stick the cut out piece in place on the background fabric if you want, but not around the edge. I pin or baste it. Then, use you needle to turn the edges under as you applique. Just before you close up an area, pull that section of freezer paper out from between the fabrics. You will get a crisp edge, a precise size, and still get the softness of not having an extra layer in there. Good luck.
