OK, I've been a lurker (I'm really addicted actually, but shy) for quite some time, but I've never felt worthy of posting my original work, so here goes... I started this project in November for my boyfriend after watching him callously incinerate the companion cube in Portals without blinking an eye... so I carefully sketched out the dimensions of the cube I wanted to make and then slowly made the pieces praying that they would come together and at least resemble a companion cube... ANYWAY, I've seen a few companion cubes on here before, but here's my take on it (and it's full-size

)... I wrote down the pattern I used for this monstrosity as I went, so if anyone is
stupid interested enough to try this I can type it up and email or post it... thanks for listening to my story to anyone took the time

...
Here is the cube pre-assembly...


Here is
my my boyfriend's cube in all it cubey goodness...

Joining (use pictures as reference)
--Center heart on circle and join.

--Center heart/circle pieces on background piece and join. Use polyfil to add dimension before finishing off.
--Join single corner pieces to double corner pieces. Long side of double corner piece to both long sides (long sides=sides without DEC). Use pictures as reference; resembles a pyramid.
--Join background pieces (sides) to form cube. Orient hearts as desired or according to reference. Fill with polyfil before finishing off; do not over stuff.
--Center middle pieces on cube and join. Use polyfil to add dimension before finishing off.
--Align single corner piece on cube and join single piece only (stitch the entire perimeter of the single corner). Use polyfil to add dimension before finishing off.
--Fold down double corner piece and join to cube. Use polyfil to add dimension before finishing off.
NOTES:--It is not necessary to weave in the ends; all ends can be hidden within the pieces of the cube or the cube itself.
--When joining pieces, you may (probably will) need to stretch and shape the pieces to get the desired look.
--Do not over stuff with polyfil; if more polyfil is needed even after finishing off, carefully add through dc. If more polyfil is needed a pencil or chopstick is useful for adding polyfil between dc.
--When joining background pieces or sides, attaching middle pieces, heart/circle, and corners, ridges are a good reference point for alignment.
--Good luck and be patient, the final product will be well worth it!
