My prejudice is purely personal and I am not trying to convert anyone here, but I have never liked glue, sewing and fabrics together. I don't even like the feel of iron-on webbing that bonds two fabrics for applique. I am sure that modern science has developed glues that truly wash away with no residue, but . . . . . And I am sure that the glue doesn't gum up the needle of the machine and then work its way into the rest of the SM innards, but . . . . . . . Well, I don't do that much quilting myself anymore, so I need all the help I can get to make it easy so I baste everything.
But I use a tailor's baste not a running stitch. It anchors everything and gives me total control. Sadly it also removes the immediate need to finish the job too lol and I have been known to leave a quilt basted for months. But I do not really enjoy quilting myself and send most of my quilts out for long arming by a friend now.
I would NEVER use a running stitch to baste a quilt as I think it leaves to much movement between layers. JMNSHO - YMMV
BTW - I hope you have realised by now that if you ask five quilters a question you are likely to get five different answers, all of them equally "correct". The legendary Quilt Police who went around telling new quilters that they MUST do things a certain way have (I hope) long-since passed into history. Ask, try and adapt. And if you find a new way that works for you pass it on. For example I asked an engineer friend to make a removable extension to the legs of my work table years ago (because he had the metal working tools the job needed) and I use quick release carpenter's clamps to "stretch" quilt backs taut on the table when I pin before basting. I am always interested in seeing how other craftsmen/women work as I never know where I might pick up a new idea for my sewing.
If you don't know how to do a tailor's baste then picture standing in front of the pinned quilt on a table or bench (pinned with quilting or sewing pins, not safety pins). Thread your needle with a long piece of very cheap thread (I use that awful "6 large reels for $5" stuff that breaks reasonably easily, not the cheap poly thread that slices your fingers through if you try to break it) and take a couple of stitches just in front of you to anchor the thread. Then - assuming you are right handed - move a few inches up (directly away from you) and take another large stitch. My stitches are anywhere from 1"-2" each depending on the density of basting I want, which in turn depends on how I plan to quilt the item. Move up and take another stitch and so on until you reach the limit of your reach. You should have a column of slanted stitches running botton left to top right. Then just take a few running stitches across (either left or right) and do the same again but working down or towards you. This time the stitches will slant top left to bottom right. Keep going up and down in columns until the whole section of the quilt on the table is done, then move on to the next section. Use just a couple of stitches to start and end threads as this avoids knots and the possibility of sewing over them, and makes the basting very easy to remove.
I might sound like a lot of hard work, but we team up and work in pairs. Each person works from the centre of the table out, and from opposite sides of the table. Having someone to chat to makes the job go fast, and most here actually enjoy basting time as they work with the same partner each time. I have a table raised so they don't have to bend over to do this, so most basting of class quilts gets done here. Two can baste a large double or QS quilt in an evening without any trouble.
The basting here is done on a laminate table. Don't try this on a good timber table as you are sure to scratch it - use a kitchen bench. But some of my students have done this at home using their cutting boards under the area being basted.
For very simple quilting (eg. in-the-ditch or cross-hatching) I probably wouldn't bother basting unless it was a large quilt. I just make sure that safety pins are placed so I don't have to remove them as I sew. But I like the reassurance this basting gives me that nothing will "drift" during sewing. It leaves me free to concentrate on the quilting - enough of a battle as I am not a confident quilter lol
Enough of my rambling! The humidity must be getting to me rofl
