I found this lovely tutorial on Karen's blog. You can find the link to a Small Design wall here and for a Large one Here . Thank you Karen!
Here is how we made mine. We used 1/2'' pipes, 2 x 90 degree elbow corners and 2 x T -shape pieces, pipe cutters and pencil for marking the pipes.
It is more easy then you think. I made my wall square, my husband cut 4 pieces of the pipe the same length - 36 ''. He used a pipe cutter.
All the pieces he used are leftovers from a pluming job.
Now you need to sew the fabric. I used white felt. I made a sleeve and put the pipe trough it.
I used little stitches.
Happy sewing!
