For backing you hoop you will need to use 2 strands of threads. Start by doing a running stitch around the edge of your fabric. This is simply a normal stitch going in and out of your fabric. When you have gone all the way around pull gently and your fabric should bunch together. Next, come up through the edge of the fabric next to your hoop and place your felt at the back. Your felt may have pencil lines on from when you cut it. If this is the case then place the side with the pencil lines down so they are hidden.
Now you do the blanket stitch. Put your needle in the felt about an inch away from the edge of the hoop. Come out right next to where you first came out and make sure your needle is in front of the thread. Pull gently and you will have made your first stitch.
For your second stitch put your needle in about an inch away from your first and an inch away from the edge again. Come straight up by the edge of your fabric and again make sure the thread is behind your needle. Pull gently and you will have made your second stitch. Repeat until you reach the end.
