I love 950F. I use it for so very many projects. I find it has a nice stiffness without being hard. I use it in blocks because it is also easy to sew thru and in my fold 'n stitch wreaths because I like them to be able to fold up and store away after the holiday and yet have a nice oomph when on the table. I have used a lighter weight on some clothing items, but my go to is always the 950F.
