The preferred way to stretch most needlecraft is by latching i.e. cross threading the piece such as John Turner demonstrates well in another thread (forum thread, not sewing thread).
However, the most common way
we stretch needlecraft is using stainless steel staples and Crescent Needle Board. This board is “acid free” and “chewy” so it takes staples well. Our stapler is a light duty one which is loaded with very fine staples, so the potential harm to the fabric is reduced, we believe. For antique, heirloom pieces, we recommend latching, however.
(Sorry, this will get a little tedious – these instructions were done several years ago for a presentation). If you have trouble sleeping tonight, this is the post to read.
This piece is crewel, but the same steps are used for cross-stitch. Cross stitch is a little easier than this HSH piece since the weave is easier to follow.
First we need to determine the frame size, whether this is to be fit into a ready-made or custom frame. We measure the “image” size of the piece and place a centering ruler in the middle. In this case the horizontal measurement was 16”, but the customer did not want a mat (mount), so we gave her as much “bank canvas” as we could.
We determined that we could effectively work with an 18-1/2” frame, so we placed the middle of the center rule on the piece and measured 9-1/4” to each horizontal side.
Place a pin at those points. Using the steps above, measure and pin the vertical points.
From each of this pins, follow the weave on the canvas to the corners.
… and place a basting stitch roughly near where the edge of the frame will be.
Follow the weave of the fabric from an adjacent pin to that point and place another basting stitch so that the previous thread is crossed. Do this for each of the four pins on each of the four corners.
This should leave you with the canvas centered among crossed threads at the corners.
Using these crossed threads as a guide, align the threads with the facing edge of the needle board.
… then staple one side of each of the corners. These initial staples are simply to keep the canvas centered while we work. They will be removed and replaced later.
Grab the canvas at two opposing pins, and
gently put even tension on the canvas, so that there are no wrinkles. Do not put so much tension on the canvas so that the fabric is distorted!
Place a staple at these two anchor points. Do the same for the two adjacent sides.
Check your measurements!!! Make sure that there is equal amounts of blank canvas on each of the four sides as measured from outermost part of the image to the edge of the needleboard.
Once you’ve determined that the piece is centered,
from the center of each side, put enough tension to the left of the first staple so that the weave of the canvas lines up with the weave in front of the initial staple. Drive another staple to the right in the same manner.
Flip the needle board 180° and do the same for this side. You always want to place tension nearly opposite from a staple from the other side.
Rotate the needle board 90° and continue as above.
Continue placing staples from the center outward towards the corners of the piece. Depending on the fabric and whether the customer has washed the sizing out of the fabric, we generally place each adjacent staple about 3/4” to 1” apart.
As you near the corners, the canvas is likely to become a little bunched up, so remove the initial four staples at the corners.
Continue with the run of staples to the end.
So you are left with a (hopefully) snug and centered needlecraft piece.
The only thing left to do is secure the excess fabric to the back. NEVER cut off the excess!!! Fold it towards the back.
We prefer “hospital corners”. We believe that there is less fabric bunched up at the corners that way so it will fit into the frame more easily.
The tape we use is a (supposedly) acid-free framers tape, although there is “fabric tape” available which we have not tried.
Flip this sucker over and it’s good to frame.
Ta-dah!
