Hello Star, as I advised
several other job seekers who commented, for this small
type of typo, I wouldn't typically recommend sending an updated resume.
Along with the cover letter for the designing
job resume, you have
several other types of letters like personal referral cover letter for designing
jobs, cover letter to accept
job offer, acknowledgement
of job offer, cover letter as a follow up
of the telephone call, recommendation letters for designing
jobs, salary negotiation cover letter, thank you cover letter after getting a designing
job.
