A Quest for Beauty & Utility through Tunisian Crochet 
Hi, I want to ask you about reverse combos: Are they made on double ended cook? In Knit-FrtBar wich bar do you mean horizontal or vertical bar? Thank tou in advance
Reverse stitches are stitches where you hook through the fabric toward you, instead of reaching to the back. This produces what looks like the usual stitches, but facing toward the other side of the fabric.
The double-ended hooks can be used with the reverse stitches to flip the work, so that you are looking at the “back side” of the fabric as you do every other row.
I have labeled the bars in a photo at https://tunicrochetweaver.wordpress.com/revised-notation/ (the Notation page of this blog).
Generally, the vertical bars are the ones that run up and down. The horizontal bars run sideways and are part of the return chain (the chain that you do on the return pass).
excelente gracias
