@lisa67 you will find that we have many witches that have a varied practice. Some don’t really have labels on their practice at all! I now just say I’m a witch, as I have evolved multiple times in my practice. Many do practice Hedge Witchery along with other aspects of the craft the resonate with them. I’m sure you will hear from them & if you have questions about it you can always ask & someone will get back to you!
We now have a masterpost about Astral Travel & Projection that has a lot of past posts & questions on the topic all in one place too! 
Astral Travel & Astral Projection along with the Weekly Challenge this week on Time Magick, where I believe that it’s mentioned 
Weekly Witchy CHALLENGE - It’s Time for Time Magick there may be other challenges that have themes surrounding hedge magic or astral travel, if you go through Weekly Witchy Challenges 
A History
Have a fun & if you find something of interest feel free to comment or ask any questions that you may have!
