I don't know about a full sew in. Do you swim? If so, how does that work?
Also, I am a BIG DIY. I don't think they do have clip ons for our hair. BUT.... drumroll!! I know that you can buy the clips and sew them on to wefted hair pieces and TADA... you have a clip on. I am sure there is a youtube video out there!! There are youtubes for everything!! Check with your hair lady. Maybe she can help.
