Great Post Ysabelle.Your post would've probably been neat if the font sizes were just normal. Next time try to minimize your highlighted words.

ReplyDeleteGreat job Ysabelle. Your post looks very neat, if it wasn't maximized, but it looks organized. Next time make your big sized font smaller. Other than that, great job.
