This kit has everything that required to be finished beside the frame.

Yes the Janlynn kit contains floss for the entire project. It is their DFN floss. I did a small kit of theirs once, but did not like the quality of the floss. If I was doing this beautiful project I would change all the floss out to DMC using a conversion chart. This would also ensure you would have enough. As you have probably read a lot of people have run out of floss when doing some of the kits by different companies out there.
