[CHAT] Advice for a huge project

Hello! I’m a long time off and on stitcher and have been wanting to embark on a large full coverage project for a while now. I think I finally found the one, and it happens to be my favorite artwork “The Garden of Earthly Delights” by Bosch. I’ve decided to go with the HEAD (I know the controversy) max size and color version (go big or go home). And I plan to do it on 25 count Aida. I was wanting to hear any advice, comments or criticism you may have before I embark. I plan on buying pre gridded and cut fabric. I was wondering what the best way to acquire all that floss is. I know a few colors I might just buy cones. I’m only 22 so I have plenty of time to work on it (I hope) Thanks!
