I recently purchased some Pegasus Hobbies pre-painted sandbags, and I must say I was very pleased. The detail in the molds and the painting standard is great straight out of the box. They fit perfectly for 28mm gaming. If you want to drop some money in sandbags instead of making your own, I highly recommend these. They sell them in straights, corners with some shorter straights, and an assorted pack of a couple small corners and more reinforced pieces. These will fit well on any 21st century battlefield through to near future and sci-fi.
