shaped bokeh lights

I've always been enchanted with bokeh lights.. Especially with shaped ones. So before I had my SLR camera, I came across a DIY shaped bokeh lights and vaguely remembered that I need a filter with a cut-out (or punched out) shape: heart, bow, butterfly, star etc.)

So without further ado, I cut out a circle in the size of my camera lens and cut out a BIG heart in the middle of it.I know that's not right. But I always google after I did something and didn't get the desired result. 

This is what I got

right side and at the top

 Look at the indicated areas.

There you can see the edges of my cut-out heart shape. So, easy to guess it was too big.

Then I googled DIY instructions and now I know how to.

I'll try to make a bunch of shapes and have fun one of these days.

I advise you to google some nice pictures of shaped bokeh lights to see what it must look like when done properly.
