Amigurumi Stripes With No Joins

One of the "experimental techniques" I tried recently was to get a lovely two-tone stripe, amigurumi-style, that didn't have joins or that icky jagged bit where you switch colours at the end of a round.

In response to a question on Flickr, I recently posted the following:

Ooooh, I just did this (can you tell I'm quite proud of myself?)...I have some pictures here: www.flickr.com/photos/noisypitta/

The way I did it was:
1. Complete one round in one colour, put a stitch marker in the loop left on your hook.
2. Remove the crochet hook, join second colour in the first stitch of the last round, then begin a round in the next stitch, counting the join as the first stitch of the round (e.g. if you're doing all sc, join colour 2 into first stitch with a sl st, then sc in the next stitch).
3. When you get to the last stitch of colour 1, put a stitch marker in the loop of colour 2 that's left on your hook.
4. Remove the crochet hook and insert it back into the loop of colour 1 and carry on with the round.

Repeat steps 3 and 4 for as long as you need. When you get to where you want to finish one of the stripe colours (in my pictures, I "finished" the white and carried on with the blue), in step 3, you just make the last stitch a sl st instead of a normal sc. Then when you come to that stitch on the next round, it's a smooth transition back to the beginning of the round.

I think all that is very confusing (it's kinda hard to describe). Best is just to try it.

(In response to: When I crochet alternating strips for an amigurumi, the stripes never look right. There is always a hiccup stitch when I start the next color in the new round. Is this typical for everyone or just typical of my bad crocheting technique? -- posted by smoochas)

I'm thinking about cabling and braiding next, and the holy grail (of course) is how to make colour joins with a round of slip stitches and not have that "step" where the sl st joins back up with the main part of the round (you know what I'm talking about, right?)...Hmmm...
