How Dense Do You Tuft?

1, Density should always depend on the yarn you’re using. I advise students to practice making small swatches while using the prongs at the top of the foot and the stitches in their previous row as a visual aid for measuring the space between your rows. In my opinion, you want your rugs to still be fluffy with some space to move but never so much that you can see large gaps or fabric between. Find the happy medium between a rug that looks and feels like it’s falling apart and a hockey puck.
This also depends on the density of the yarn. We use wool that is rather dense so if we were to tuft too densely. This would cause the rug to start curling backwards because of all the excess pressure on the front. So that’s another thing to keep in mind.

2, I go pretty dense my goal is when standing on the finished product I don't sink into the rug.

3, I go in pretty tight.. gives me more to carve away and I get massive compliments on how thick they feel when they are done.

4, I'm 100% in the minority but I absolutely swear by tufting with the lines a bit further apart. There's some spaces toward the right where I could've gone a bit closer, but I love the way the rugs feel after this. As long as the edges are super thick to prevent the fabric from showing, I much prefer to do it this way.
