I don't like too much cleavage when all is seen to the waist. But something we can do. To fix the neckline is not difficult.
 

Here is a tunic I recently acquired. It's light, airy cotton with a beautiful print in turquoise with purple flowers. She's got long sleeves (which I prefer). The problem? Of course, the neckline sits too low.
 

I looked in my drawer and found two pieces of knitted fabrics that are suitable in color to the tunic.
 

I used the t-shirt that I stitched previously. He had some stretch lace on it, which was a good bonus. I cut strips about 10 cm wide purple and 2.5 cm wide turquoise color. Now sew them along the long sides.
 

Here's how it looked after.
 

Now place the strip between the front and back of the tunic so that the piece is symmetrical sitting on the neck and closed V-neckline to the desired height. Don't worry about the excess fabric on the inside. We'll take care of it later.
 

Now manually baste a piece of fabric. I know most of you cringe at the thought of sewing by hand, but this step is important. Just make sure that this part will remain in place for half an hour maximum. That's all you need.
 

Now set the sewing machine to the minimum speed and length of the stitch that is used in the original clothes (You don't have to be exact, just make about) now sew a seam on the original seams of the neckline (preferably). It will be good to not have too many seams at the neckline, because it is a very noticeable piece of clothing and too many seams might make it unattractive. If you go slowly and calmly, it is not so difficult to follow the original seam.
 

Here is the fabric on the inside. Now we can cut off the excess fabric.
 

So much better!
 

Here is a tunic modelled on me. Any neckline! Yay!
 

I could leave it at that for the moment, but since I had a few more minutes, I decided to decorate the tunic. It was an interesting print at the hem and cuffs of the sleeves. I decided to see if I can recreate the pattern on the neckline.

To do this, I slipped a solid paper (insert color ads from the Sunday paper) between the front and rear of my tunic. This will prevent any leakage of paint to the back of the tunic while I'm putting in the front.
 

Then I took colored markers and fabric paint. To draw on with fabric markers easily enough, but if you've never done this, just try it first on a separate piece of fabric. I couldn't draw the whole motive, but I think that my drawing have a fair resemblance to the original design. Then I filled a large flower in the middle yellow paint for fabric. Then I put the tunic on a flat surface to dry approximately 2 hours.
 

And that's all! The tunic was finished. I have received many compliments when wore it to the office.
