For a more finished appearance, rugs and wall hangings should be bound. You can use either use a sew on binding or an iron on.
To finish without binding, cut canvas at least 3 holes beyond the outside edge of the design, then cut the corners diagonally, fold to back of rug , match mesh and baste in place.
To finish with binding, cut canvas at least 3 holes beyond the outside edge of the design, then cut the corners diagonally away from the pile.
Then with right side facing you, sew one edge of the binding as close as possible the knotted edge. Turn so the back is facing you, then fold back and sew the other edge of the binding to the back of the rug. Miter corners and stitch down.
I also suggest that you use a rug backing such as saf-t-bak or they sell a fabric backing in most craft and fabric stores for non slip or limited slipping.
Finishing a Wall Hanging:
Start at upper corner, sew on binding around both sides and bottom of the rug Then with right side facing you, sew one edge of the binding as close as possible the knotted edge of the top of the rug, turn over so the back is facing you, then sew down making sure you will have enough room to insert a rod or piece of dowel through.
Alternatively you can just bind the rug in the normal manner, then to hang, sew on large wooden curtain rings, slide over a wooden rod, add wooden finials to the ends of the rod and hang.
HOOKING & BINDING OTHER THAN RECTANGULAR
Starting at the left hand side of the design hook across one row at a time, making sure not to go outside the edge marking the limits of the design.
When hooking is completed, trim the unworked canvas approximately one inch away from the design & TRIM TO SHAPE .
SEW TO BACK
Ensure you sew securely to canvas, not the hooked yarn. Sew these securing stitches at the intersection of the trimmed edge of the canvas.
SEW ON BINDING
Sew on one side of binding around the outside, then easing the fullness, making small pleats if necessary to the binding and evenly sew the other edge.
You should use small stitches so that every square of the canvas is caught along the outer and inner edges of the binding to insure against unravelling during cleaning
HOW TO MAKE LATCH HOOKED PILLOWS
Hooking a pillow or cushion cover is exactly the same as hooking a rug.
When the hooking is finished trim the unused canvas leaving 3 or more holes around all sides of the hooked area .
Cut a piece of strong backing fabric roughly the same size or a little larger then the canvas area .
Place right side of fabric backing face to face with the right side of the hooked canvas (the side with the long ends the good or outer side !) and baste or pin into place.
Hand sew three sides as shown, and trim excess canvas and backing from stitch line. Clip corners and turn right side out.
Fill with pillow stuffer, down or other material. Hand sew opening.
