A glue stick makes faster, flatter and longer-lasting joins than tape when you assemble a tiled PDF pattern: trim one edge, run the stick along the margin of the page underneath, press the next page onto the alignment marks, and the result lies flat, folds without lifting and can be cut with a rotary cutter without gumming the blade. Tape wins when you need to reposition a page, when the surface under the paper must stay clean, and for repairing a torn pattern. Most sewists who assemble patterns regularly end up with a glue stick for the joins and a roll of tape for fixes.
How do tape and glue stick compare?
| Feature | Tape | Glue stick |
|---|---|---|
| Speed per join | Several short pieces, or one long strip to tear and place | One swipe along the margin, press, done |
| Repositioning | Lift and re-stick once or twice | About 10 seconds before it grabs |
| Flatness of the join | A ridge where the tape sits | Flat; the overlap is only paper |
| Durability | Curls and lifts at folds; yellows in a year or two | Stays stuck; the paper fails before the glue |
| Cutting through | Gums scissors and rotary blades | Cuts like plain paper |
| Pressing with an iron | Melts and ripples | Fine on low heat with a cloth |
| Cost for a 40-page pattern | A good part of a roll | A fraction of one stick |
| Mess | None | Slight, if you glue past the margin |
| Repairs | Excellent | Poor on a tear |
| Transparency | Clear tape shows lines through it | Not needed; lines are on the top page |
How do you assemble pages with tape?
Trim the overlap margin on one edge of each join, usually the top and the left, following the maker's scheme. Lay the trimmed page over the untrimmed one so the alignment marks meet, hold it with a finger or a weight, and tack the join with two short pieces of tape at the marks. Once the row is tacked, run a long strip along the full join, or add a piece every 10 cm (4 in).
Use matte invisible tape rather than glossy clear tape. It can be written on with pencil, it shows less of a ridge, and it ages a little better. Washi or masking tape is repositionable and gentle on paper, but it loses its grip within weeks and is a poor choice for a pattern you want to keep.
Tape's great strength is forgiveness: a page placed a millimeter off can be lifted and set again. Its weakness is everything that comes afterward: the ridge at every join, the tape that curls when the pattern is folded, and the gum on your shears when you cut along a taped line.
How do you assemble pages with a glue stick?
- Trim the same single edge per join as for tape.
- Lay the untrimmed page flat and run the glue stick along its overlap margin, a strip about 1 cm (3/8 in) wide, staying outside the cutting lines so the glue never touches a line you will cut.
- Place the trimmed page on top with the marks meeting. You have about ten seconds to nudge it.
- Press the join with the side of a ruler or your palm. Move to the next page.
- Assemble rows first, then join the rows to each other, so you are never gluing a long edge in one go.
A purple glue stick, the kind that dries clear, shows where the glue is and whether the strip is even. Use a glue stick made for paper. Liquid craft glue soaks the paper and buckles it, and the pieces will not lie flat.
Let the pattern sit for a few minutes before folding or cutting. The glue sets fast but gains its full hold as it dries.
Which is more accurate?
Glue, in practice. With tape, the first piece tends to catch the page slightly before you intended, and tacking at two points then taping the length can pull the page by a fraction. With glue, the whole margin is held at once, the page can be slid for a moment, and it stays exactly where it was pressed.
The accuracy of either method depends far more on aligning the marks than on the adhesive. Match the printed crosses or triangles, not the edges of the paper, and hold the pages up to a window or a light table when the marks are hard to see through two layers.
Which lasts longer?
A glued pattern lasts as long as the paper. Fold it, roll it, trace from it in a year, and the joins are still flat. A taped pattern starts to lift at the folds within a few months, especially in a warm room or a drawer with other paper pressing on it, and clear tape yellows and goes brittle over a year or two. If you keep patterns, as how to store PDF sewing patterns describes, glue is the better foundation.
Pressing is the other difference. Pattern pieces that have been folded sometimes need a pass with a dry iron on low to lie flat under the fabric. A glued pattern takes it; a taped one does not.
Which costs less?
A glue stick costs about the same as a roll of tape and assembles several large patterns. A 40-page pattern uses a good part of a roll of tape if you run full-length strips, and tape is the thing you run out of on a Sunday evening. On cost, glue wins comfortably.
Are there other ways to join the pages?
- Double-sided tape. Flat like glue, quick like tape, repositionable for a moment. It costs more and the dispenser can be fiddly, but it suits people who find glue sticks messy.
- A stapler. Fast and strong for a pattern you will cut once and discard. The staples make ridges and catch on fabric, so it suits a toile pattern, not a keeper.
- No-trim methods. Some makers print a margin on one side only, so you overlap without cutting. Others let you fold the margin under instead of trimming it, which saves time but leaves a thick edge that is hard to align.
- Assemble only what you need. Use the page map on the cover and print only the pages of the pieces you are cutting. Patterns that number pages by row and column, A1, A2, B1 and so on, with a map showing which piece sits on which page, make this easy; Sewly's PDFs do that and skip empty pages, so a skirt is often eight or ten pages rather than twenty. The assembly guide goes through reading the map.
What goes wrong with each method?
With tape: joins that drift because the first touch caught early, ridges that catch the rotary cutter, pencil lines that will not take on glossy tape, and the tape itself lifting when the pattern is folded for storage. With glue: a strip run over a cutting line that then tears when you lift a misplaced page, too much glue near the edge that buckles the paper, and a dry stick that holds nothing. Keep the cap on and replace a stick that has gone crumbly.
Both methods share the worst mistake, which is aligning paper edges rather than marks. The PDF pattern printing mistakes post covers that and the print settings to check first, because no adhesive fixes a page that was printed at the wrong scale.
Which should you choose?
- You assemble patterns often and keep them: a glue stick for the joins, tape for repairs.
- You are assembling your first pattern: tape. It forgives a misplaced page, and you can switch to glue once the marks and the trimming scheme feel familiar.
- You cut with a rotary cutter: glue. Tape gums the blade and the ridges deflect it.
- You are assembling a toile pattern you will cut up and discard: either, or a stapler for speed.
- You work on a table that must stay clean: tape or double-sided tape, with the pattern on a cutting mat.
- You press your patterns flat before use: glue, every time. Tape and a hot iron do not mix.
