Thanks so much for the great tips! I have many projects kitted with the DMC or hand dyed floss as well. I find it easier to have individual floss for each kitted project separately.
My kitted projects are kept in rubber maid containers and the fabric is either rolled or folded (especially if I havent started stitching yet). Some designers or companies I will have several projects in the same large container. Then the projects will be kept in clear protectors and a three-ring binder and the different sets of floss will be kept in separate (by project) Ziploc baggies however in the same large container. It hasnt failed me yet and there are about 25-30 medium to large projects kitted and ready to go.:)
