First of all you need Martha Stewart Loom. Attach the loom piece so that the shape resemble a heart.
You also need 2 colours of medium sized yarns (If you plan to use local yarns like nona/minlon, I would suggest to use 3 strands of yarns at a time)

After binding off, the woven heart will shrink a lil bit and it will look like this
The woven heart can be used as a placemat, coaster, pillow, and everything you can imagine :)
Below is my woven heart pillow~
Isn't it cute? (^_^)
