Fix Blurry UI text?

When I was building this UI, I didn't realize that resizing by pressing T and dragging the windows, I would totally screw up the resolution of any image I was resizing, and only later did I realize I should have been using the scale instead to preserve the resolution. That said, now I have a nearing completion UI that's starting to look bad, but my problem is that this UI is for a crafting menu. That said, because of the simplicity of the inventory system, I made the text contained in the UI and actual UI is a game mechanic just for ease of construction (i.e. if a light turns on as a result of the item existing in your inventory, then the condition for the craft button OnClick function is met and you can craft it). So I really don't want to destroy the UI and start over from scratch overlaying all the images and such, because that would mean a lot of backtracking on the game mechanics themselves as well. Is there some way I can set the UI elements all back to their respective default resolutions without getting rid of them, resizing them using the scale tool this time instead of changing the aspect ratio (i think that's what it is I was using?) to avoid destroying it and starting back from the beginning? Here's a screen shot to show the resolution deterioration I'm referring to as I created more panels on top of panels. This isn't the whole UI, but the other screenshot exceeded the limit, but there is another behind this one also. The text in the bottom left of this was created second (after the panel that's behind this one) and then the text on the right in that selection box was created third, and even between these it's pretty easy to see and by the time I got to the text in that menu on the right, It became near illegible. Thanks in advance for any help you guys might have
