Cost effective(free) Valentine's plushie

With Valentine's coming up, I've been looking through the 'ibles for valentines gifts, didn't find anything that suited my situation. So I figured I'd make a plushie for my lady friend. The middle heart was designed to be removable but I ran into some trouble. Look at Step 4 for mistakes.

Step 1 Making the pattern

If you want to make this, before you start take a look at step 4 to see the mistakes I made.

Find heart shape or draw heart shape you like. Draw the big one, scale it down/or draw it smaller inside. Use some sort of string or usb cable to measure how long the sides will be. The side strips gives it the 3D shape. Make the side strips a few more cms longer just in case. I split them into two because I'm using a shirt not a big piece of fabric. Oh thats CM.
