Tapestry crochet in the round

[Nicolapen]

Trying Tapestry crochey in the round. Did 4 rounds back loop only single crochet no colour changes and no carring of yarn Then did 6 rows back loop only single crochet with several colour changes carrying the yarn throughout. The 4 bottom rows are wider than the 6 with colour changes. 

I also tried single crochet stitches in both loops with the same issue.

Is this to do with tension of the yarn? 

When I do the colour changes I complete stitch in new colour. One change the old colour I bring to the front the other the old colour stays behind so one ball stays on the left and the other on the right without twisting the yarn

Same yarn?

Most likely your tension.  Tightening a bit when you do the color change.  Very difficult to get perfect tension.  🙂

Thanks for taking the time to reply. The yarn is the same. I have frogged my work and decided to do stripes instead. See attached photo for new project
