Just a tip that's worked for me for a long time...
As I built skill, I discovered that I was not establishing the stitches tension over the index finger as in knitting but through my thumb and middle finger.
Holding the work with my thumb and middle finger just below the row I'm working allows me to keep the fabric taut and the loops I pull through even with the ones already on my hook every time...Even creating a chain, holding the chains stitches firmly, moving my fingers along it's length as I increase is how I establish and maintain tension!
It may work for you!
Good luck with your projects, I look forward to seem them!
P.S. another small thing about the base chain...If you always hold your hook sideways, (front point to back handle) when making it, the loops will all be the widest width of your hook and your stitches will be even and identifiable, especially the end one's that sometimes get missed. Overall, your chain won't be to tight to work!
Hope I've made sense
