I do same as tartan..zz the pieces together. But more often join w/ the interfacing strips because it is faster for me and the fusible is much cheaper than the batting tape. I always have scraps of interfacing that I save for this.

I use fusible interfacing, I buy the cheapest I can find, when JoAnn's has a sale I can stock up for $1.00 a yard. I cut it to the width and length I need. A lot cheaper than batting tape and it works the same. If you are using the polyester puffy batting you will melt it so hand sew or machine sew it together.

I have zig-zagged pieces together and used the tape to join. When using iron on tape, place a piece of parchment paper over the area so nothing sticks to your iron.

I overlap the batting by about 2 inches and cut. This way the edges are exactly the same when I separate them to sew together. . I sew them together with a zig zag but use the stitch that has multiple small stitches in each zig and zag. This works perfectly for me since i use that stitch.

Krista Moser has post on her blog showing different ways to join batting that is very helpful. https://www.kristamoser.com/post/how-to-piece-batting

Its called "Batting Tape" You can find it at Nancy's Notions for one place and I'm sure other online sites have it too. It comes in a couple different widths too so I order the 1.5 x 100 yds size.

I keep the larger pieces and attach them to others close to the same size. I keep a paper with what the size is afterwards pinned to it so I know the size before I add another section to it. Any small pieces that are at least 8 x 8 and larger I keep for embroidered quilted blocks or for adding to pillow covers I make. I also use it for when I'm reunholstering chairs or embroidered items for picture frames.

Years ago someone posted a suggested way to join scraps of batting. Basically, you overlap the two pieces and using your rotary cutter you cut a serpentine line through both pieces. Then, butting the pieces, side by side, and using a wide zig zag stitch you join the two sections. I have found that this avoids lumping and makes the two pieces of batting lay quite flat. So when I need to join batting, this is my go-to method.

Many thanks to you, and all the rest. However, as I'm a newbie, what are QAYG strips?

I too zig zag mind together by butting it up against each other being sure that the line up has a good straight edge. Since I use different bats that sometimes look alike I keep each bat scrap in separate bags so I don't mess up.

Quilt As You Go.
Basically layer the backing and batting. Then lay your first strip on top. Sew it along the edge to hold in place. Put the next piece on - right sides together just like normal, but when you sew it together with your first strip- you will be attaching to batting and backing at the same time. Flip 2nd piece face up. Grab 3rd strip, right sides together w 2nd piece. Sew. Open. Continue....
