How to sew a rip in an awning.
When you take on fabric awning repair and reinforcing the seams you should use a cross or saddle stitch.
Unlace the awning far enough that you can lift up the corner.
Set your board up under the tear before you get started and flatten the fabric.
These are adequate stitches but not the strongest.
Once you have the fabric you ll want to sew the path on the underside.
Once the rectangle patch is securely attached to the awning then you will want to carefully stitch the edges of the gash to the newly attached fabric.
Follow the same procedure as for rips in the fabric body cutting your repair fabric long enough and wide enough to extend beyond the rip.
Most awning fabric uses a single or double stitch to seal the seam.
You can either use waterproof glue or sew each patch on.
Draw the edges of the rip as close together as you can.
Glue it in place from the underside pressing it well.
Apply any tape or patch carefully to the canvas once part of the tape is down it should not be removed even if it is on incorrectly.
