I have made some using old feeds sack. I cut the top off to the size of bag I like and use the top for a handle. I use some wild bird seed bags they are so cute. but make sure you cover up the UPC code on the bag I have buy lot of bags of bird seed that was not bird seed at all. I put a small peice of bas tape at the top for the checker to hung it by they seam like that and it help keep the bag up as they fill it.
I have got old placemate to use as a bottom for some of my bags. they are stuff and can be cut to size. and come on all colors. found my it the good-well for next to nothiing.
