What is the largest design size you can do on the 3.5 inch by 3.75 inch frame Thanks Anand When I ordered the pocket hoop, I knew I had a baby Christmas stocking that needed to be done, so I just ordered it. But, I did call Melco Mart and found out the following: 2.5 X 3.75 inches is $84.95 3.0 X 3.75 inches is $94.95 3.5 X 3.75 inches is $104.95 Also, you need to get the hoop gauge which is $96.95 and will work for all three sizes.
