I really appreciate the splendid effort put into this course, but could it be possible not to use "eski" excessively in every example, "yeni" for time to time would be wonderful! Thank you!

red towel is a adjective with a noun. Does this need a different suffix?
Nope, no suffix is needed when combined adjectives with nouns :)
"Red towel is so old." why this wrong?
"Red towel is so old." is not a correct sentence in English. You need to say
"The red towel is so old."
By the way ,"The red towel is too old" is correct ,too.
