I make these to take over gifts, kids love them because they can haul away the gifts they get in the bags. You could make them from a fall themed shirt if you wanted to make it a trick or treat bag. The bag is lined to make it less stretchy. I cut the ribbing off the bottom and turn it into a turn down for the top of the bag, the handles are cut from a sleeve.
Some of the pics are a bit blurry. When you sew the ribbing to the bag top, you will have to do a lot of easing. You are sewing two stretchy fabrics with a non stretchy fabric in the middle so there might be some pinchy pleats but they won't show as they will be hidden by the folded over ribbing.
this is how I cut the shirt up, I trim the seam allowances from the ribbing on the bottom
this is how I cut the handles. I cut them four inches wide, fold and press with raw edges to wards the center and a ribbon sewn down to cover the raw edges.
sew the lining and insert it inside the bag. I have to adjust the length of the ribbing to fit the opening. I insert the handles so that when the ribbing is sewn down it can be folded over the top of the bag and the handles are sewn up in between.
here is a blue bag finished
finished white bag
the wrong side of the white fabric looked like snow to me
so I made this mini snowman pillow. It would look cut on a mantle or credenza
