The simple reason curving text as part of a DIY project is always worth doing is that it stands out a lot more than straight text and looks like you’ve put a lot more effort into crafting it. You can also make some extremely creative designs using text that is curved such as having two blocks of text above and below each other that curve in opposite directions to almost make a circle shape which is a lot of fun to try out for parties and gatherings.  It also means your designs won’t look too long and makes them look a lot more appealing than if it was hanging straight. It also grants you a bit more space for other decorations which is never a bad thing.
