I have done several hates on the round looms and they have never turned out. They have all had a wide spacing at the first and last stitch. So I went out and bought some new looms thinking the looms were the problem instead of the loomer. I purchased the kb Hat Loom, set it up for the child size hat with all the pegs for that size and went to work. I used Bernat Softee Baby yarn as I wanted this for my 2 year old granddaughter and it needed to match the scarf I made her for Christmas. In my previous attempts to make a hat I had used two strands of yarn held together, but this time I only used one. Following is how I ended up making the hat.

Cast on using the e-wrap.
For the first round, k2, p2 all the way around.
Continue with the k2, p2 for your desired width for the brim. I stopped at 1 ¾”.
Continue to knit each round using the u-wrap stitch until you reach desired length of hat. I went for 7” including the brim.
Use the gathering stitch to remove from loom.
Close up opening. Add Pom Pom, if desired.
