Clara Bow Panel Jumper - stitching together

I feel like I've been working on this jumper forever! I think I chose a tricky one here as it's 80% K1 P1 rib... which takes aaages!! I have, however, finally got to the point where I have finished both front, back and both sleeves... Yay!!

All pieces present and correct



 But now comes the boring bit... I've heard many knittists say that they really hate the stitching together part. I've heard it said that they have kept the completed jumper/cardigan in their to-do pile and moved on to greener pastures. I couldn't work out why, they were so close to having it finished! Just one step away and it's a wearable piece!
Well.... I get it now...

Stitch.... by stitch.... by stitch...

I had this fella spread out on the living room floor (I've read up and it's apparently easier when it's laid out on a flat surface), and began to stitch the sleeves to the front and back armholes.
Then my back gave out... Well that's an exaggeration, but it wasn't a comfy position to be in. Plus every stitch I had to really focus on, make sure it was as smooth as I could get it (it's still a bit Frankensteiny). I managed the sleeves and started on a side seam... then I gave up.

by stitch... by stitch... by stitch

This is a booooooring part of the knitting process!!
I would in fact avoid it if I could. But then there would be no jumper, and this would make me sad.
I have taken an executive decision to stop for the evening, then continue again tomorrow to get it finished.
