What I've done in the past is this: flatten out a coffee filter or paper towel; write the variety name on them with permanent marker and then spray the filter or towel with water (I use distilled water for this). Put one variety of seed on the damp towel/filter and then fold it up so that the seeds can't fall out. Make a packet for each type of seed. You can put multiple packets in the plastic bag but don't pack too tightly as you need a little air circulation. I store the baggies in the butter keeper in the fridge so they don't get lost. You shouldn't need a separate bag for each variety since you've already labeled the individual packets.
