Double borders are the answer when you have frequent colour changes, to save having to sew or weave in ends - and essential for mosaic crochet where you change colur each row..
Bear in mind that mosaic crochet is double thickness so a thick border works very well. You might not like the look on a single thickness blanket so do a test piece first.
You may also have to make some adjustments in the slip slitch foundation row if you have stitches of different heights at the edge. Mosaic usually has a single border stitch to work into.

I have tried double borders and was not happy with them.
As for mosaic crochet, I really admire blankets and throws made using this, they look very impressive. However, I found it so boring! I did half a blanket and sold it unfinished with all the extra yarn on an auction site.
