Now that your fabric is cut out, thread your needle, and begin sewing in and out all around the edge of the fabric.
Once you have gone almost all the way around the edge of the circle you can add your stuffing. Then continue to sew all along the edge until you reach the place you started.
I used poly-fil from Joann's (I bought it in bulk a while back on sale, but you could also use grocery store bags for a thrifty option.
Once the pumpkin is filled with the stuffing of your choice, finish sewing around the edge until you get where you started and tie a tight knot.
After the knot is tight as the top, I took the needle and stuck it down through the middle of the pumpkin (where the stem will be glued), and then wrapped it back to the top and tied a knot.
The last step to making fabric pumpkins with real stems is to grab the stems I saved from last year’s baby pumpkins and hot glue them to the top.
