 Once you have 48 LEDs bent you can then bend the LED legs for column 4. Take 16 more 3mm 
 LEDs out of your kit bag and bend each LEDs long leg in the same way as you did for the 
 previous LEDs; however this time 

 DO NOT BEND 

 the short  leg... 

 You should now have a total of 64 LEDs, 48 with both legs bent, and 16 with just the long leg 
 bent. 

 Step 2: Making the first row 

 The next step is to take some of the LEDs you have just bent and solder them together to 
 make the first row of 4 LEDs.  If you purchased the optional template PCB you will now need 
 this to construct the grids. Otherwise please see the section of this document titled 
 ‘Template’ for instructions on how to make your own.
