travelling garter squares

This is a post for my sisters.  Between us we are knitting up some hand-dyed, handspun from the "stash" (yarn stash, separate from fabric stash)  So girls, here are the instructions:

1. Using 6mm needles and the hand-dyed, handspun, cast on 29 stitches.  Yes, 29, not 30.  Cast on using the double method, where you push the needle behind two strands of yarn not one.  See top photo.
2. Knit 49 rows. Knit every stitch.  No purling, and no slipping the first stitch or anything fancy.  You are up to 49 rows when you can see 25 "ridges" and the starting waste yarn is on the bottom left corner.
3. Cast off.  Not too tight.
4. Your square should be approximately 7.5" square.  Don't fret if it is not exactly that size. 
5. Both start and end waste yarn will be on the same side.  Leave a good tail so there is spare to sew with.  

Repeat steps 1 to 5 until you can't stand it anymore or run out of yarn.

I am thinking about a hundred squares.  I have done 5, so 95 to go.
