Incase you can't tell, I love a good text path! They make your pages more interesting and you can fit text into odd shaped spaces. If you purchase a pre-made text path like my Text Path Blenders, you may find you have the perfect text path shape - but it's flipped the wrong direction... You flip the layer only to find that your text is now backwards or upside down. Well, that's no good, lol!
Here is a tutorial on how to flip your text path in Photoshop.
You will need your opened text path (you can use regular text paths - step 1 only - or my Text Path Blenders). If you are going to use your Text Path Blender on a page layout, you will want to flip it in the original document. If the size of the document is changed (like when you move it to your 12x12 page) the mask will not line up with the path correctly.
If you need a Text Path Blender to test this out with, you can grab a free sample here.
1.) Click on the text layer and go to Edit -> transform path -> flip horizontal (this flips the path, but not the mask).
2.) Create a new layer above your text layer.
3.) Click and hold on the mask (black & white box to the right of the text layer) and drag it to the new layer.
4.) On the new masked layer click the little "linked" icon to the left of the mask to turn it off.
5.) Click on the new masked layer and go to edit -> transform -> flip horizontal (now your mask is flipped)
6.) Click and hold on the mask again and then drag it back to the text layer.
7.) Click the little linked icon between the mask and the text path again to re-link them.
Hope you find this tutorial useful! I'd love to see how you use it - link me up in the comments or let me know if you have any questions!
