Thanks! It's always good to get feedback and support! I've been somewhat stuck on a creative rut these past couple weeks, as well as attending to other things (like the upcoming xmas season). I've been thinking of doing more of those sculptures though. I am interested in so many creative mediums, but my life stresses cause a bit of mental block currently. Hopefully I'll get through that soon. Thanks again!
PowerRename is your friend (in the MS PowerToys suite) for this sort of thing, if you're on Windows :)
Thanks for the tip saltedslug. I already have a program called "Advanced Renamer" installed and know how to use CMD and PowerShell too, but I'll keep the program you recommended in mind for if I have problems! Thanks!
