How can i do french manicure at home ? help?

Grab a stiff bristled paint brush, acetone polish remover, white polish, and clear polish. Paint the tips of your nails with two coats of white polish. the lines don't have to be perfect...that is what the paint brush and Acetone are for. After your tips have dried, take the paint brush and dip it in the acetone, (not too much) then sweep the brush along the ';unfinished'; side of your white tips. Acetone is an instant polish remover so i like it better, you can leave the tips as thick or as thin as you'd like. After you're finished perfecting the french tip lines with your paint brush dipped in acetone, paint a coat of clear polish over your entire nail. It's inexpensve, you can do it yourself, and your nails will look GREAT!
