I am putting one of my popular weaving tips on this post. It is a technique I use all the time. I always make long warps and cut off the pieces as I weave them. I use this at the beginning of the warp, too, an make a sample then put in the heading again to cut it off. When you hook up the warp again, it will be on tension because the sticks were put in with the warp on tension.
This is taken from my book, Weaving for Beginners, beginning on page 134.
The two-stick heading
This is a very useful heading. I have used it countless times. One reason is to
eliminate the knots on the apron rod so that the cloth rolls up without lumps
on the cloth beam. Another reason is so that you can cut off some of the cloth
before the whole warp has been completedly woven.
You need a pair of sticks that fit on your cloth beam and won’t interfere with
the ratchet.
They can be lease sticks, dowels, or metal rods. I prefer thin and lightweight
sticks rather than thick ones because they take up less warp and aren’t so bulky.

After you’ve woven the initial heading to spread out the warps (page 105)
(or at least 1″), insert a stick in one plain weave shed; insert another stick
in the next plain weave shed, and continue weaving for 1″, or so. See
Figure 307. The lease sticks will stay in place because they are woven in the cloth.

Release the tension on the warp, and carefully cut between the knots and the first inch of the heading that you wove. Leave both plain weave sections and the sticks attached to the loom!
Remember, you are cutting between the knots and the cloth which means only the knots are being cut off—the heading remains attached to the loom because it is part of the warp that is on the loom. Be careful not to cut the loom’s apron cords! See Figure 308. (If you want fringe, see Figure 311).
The heading will be re-attached to the apron rod. See Figure 310. If the warp is sparse or slippery, put some white glue or tape on the cut edge to prevent the heading from unraveling or the warp threads from pulling the heading out when the warp is back on tension.

Fold the first stick, with the first inch of the heading, under the second stick and the
second inch of the heading. See Figure 309.

Tie the two folded sticks across the front apron rod at 3″ intervals. Make the ties
strong by doubling a sturdy but not fat string. Use a tapestry needle to go through
the cloth and around the rod. Make the first tie in the center of the warp to hold the
sticks stable. You might find it easier if you wind up the cloth apron until the apron rod is resting on the breast beam. Then pull the heading sticks (and the warp) forward to the apron rod and tie them to it, while steadying them on the breast beam. Put the knots on the front edge of the apron rod so you won’t make lumps with the ties. See Figure 310.
Begin weaving again. The warp tension remains unchanged; since the heading
sticks were woven in with the warp on tension before the knots were cut off, all
the threads remain evenly tensioned as you resume.
FRINGE
If you want fringe, untie the knots instead of cutting them off and fold the
sticks as above. Then smoothly fold back the unknotted warp threads as well as
the heading.

Another situation: Cutting off the cloth as you go
You can cut off pieces as you weave them; it’s not necessary to wait until the
entire warp is used up before cutting off the fabric. The headings and two sticks save precious warp because you don’t need to tie the warps back on to the apron rod.
When you’re ready to cut off a length of cloth, make the complete 2-stick
heading just as above. (Weave 1″ of plain weave, insert 2 sticks into the next two plain weave sheds, and weave one inch more. That’s the complete heading. You do not leave any space between the cloth and the heading—you’ll just cut the cloth and heading apart.
Cut between the cloth and the first inch of the heading you wove, leaving the
complete heading attached to the loom. See Figure 311. Remove the cloth from
the front apron rod. Fold the two sticks, and tie them to the apron rod, as above.
Thank you so much. I often have very long warps when making multiple scarves or table linens. I find myself carefully unwrapping the entire warp while still on the loom and rewinding it. This is a much easier solution.
Your information on your website is very helpful. Thanks.
The best ideas are the simplest ones. A fabulous tip, thank you Peggy. I can see this coming in very useful on many occasions.
