actually i have a (thrift)store bought couch that fits my MSD ill take a snapshot and measurements for you real quick and upload it to my scraps. it can give you a range to start with. dosn't have to be 'perfect' since couches come in so man different styles. mine in the tut really has arms a bit too low(forgot to compensate for height difference after i padded the seats)
hehe glad you like it.. the 2nd tutorial to go along with this one(covering a chair instead of a couch) ended up on the back burner because of design indecision but i think it will actually be done soon..
it will be posted to all the same groups when it is..
well i used 3 boxes for mine, the seat which was cut to the length i wanted. then a keyboard box with about a centimeter cut off the bottom of one side so it angles back. and then i had a large thin box that i cut 2 corners off of for the arms/sides. then just taped it all together..
if you need any help i have no problem giving some O.o
