Sure thing, Pippi21.
Since I needed those seedlings to grow on as separate plants and not have their roots entwined, I just separated them into the bags to grow them up a bit more while waiting for my garden soil to get warm and dry enough to plant them out. I make the bags up over the wintertime - they're cut (to make them slender, but as long as possible) doubled, with the edges taped to make a rather cone-shaped cup, and they last just long enough to make sure there's a firm plug of handle-able soil for transplanting into the garden. These work great for plants that don't normally respond well to transplanting; like poppies, larkspur, pansies, morning glories, and anything else with a long taproot. I just plant the whole thing; what's left of the bag, and all.
