These are the straps I designed for the secret hex bag.  Below are charts, written instructions, and a video.  Plus a bonus alternate two-row version.  Yay!

My suggestion is that you look at the chart, watch the video, and go for it.  If you absolutely must, read the written directions, but they are super-wordy even though the straps are pretty simple to make.




Granny Strap Written Directions
Row 1: Make an odd number of foundation single crochet (fsc)  stitches.  

Stop making that face ... it's easy!  If you don't believe me, click through to my tutorial and read all the comments that say how happy everyone is that they finally learned to do fsc.  You can do it.  Trust me!!!  My tutorial has a video and step-by-step photos.  And, you can ALWAYS email me.  I bet you'll have it mastered in 10 minutes, tops.

Row 2: Make two single crochet (sc) stitches in the top of the third fsc, chain 1, * skip 1 fsc, 2 sc in next fsc , chain 1 repeat from *  until you get to the last fsc.  In the last fsc make 2 sc (in the top of the fsc), chain 2, 2 sc (in the side/end of the fsc), chain 2, 2 sc (in the bottom of the fsc making sure to catch center bar of fsc so there is no yarn between the 2 sc in the top of the fsc and the 2 sc in the bottom of the fsc), chain 1.

Skip an fsc, 2sc in next fsc, slip stitch to top of first sc of Row 2, pull a loop through the last stitch, cut yarn and pull end through, and tie a square knot on the back of the strap with the beginning and ending yarn ends.

Row 3: In the chain space to the left of the start of row 2, make 2 sc, chain 1, * skip 1 fsc, 2 sc in next fsc , chain 1 repeat from *  until you get to the 2 chain corner.  In the 2 chain corner make 4 sc, chain 1, in the next 2 chain corner, make 4 sc, chain 1.
