How do I??
 

I remember seeing information on this board before on how to sash blocks in nows and keep them lined up so that the sashing strips are in a straight row vertically. I am having difficulty with this after I sew my blocks in a horizontal row (which works out fine) but then trying to line them up in the vertical rows. I think it was information provided by Hollis but I'm not sure. Can anyone help me please?

I use a pin to mark the seams.. So when i lay it on top it will match up..

Create your horizontal rows. Attach a long sashing strip to the bottom of the first row. Iron, then turn it over to the wrong side. Use a pencil and ruler to mark the seam lines into the sashing strip. These become the sashing's "virtual" seam lines. When you attach the next row to this sashing strip, first match up and pin each seam to the marked line in the sashing strip. As you sew, ease or stretch the blocks as necessary to make sure the seams are lined up with the markings. This ensures that the rows line up when you are done.

As suggested, mark the lines to square it up to.
Plus it's critical that each section is square and each block equal in size. Then you need to make sure your sashings are all the same length.

Cornerstones can help to simplify and make it easier to keep all straight and square.

Yes, I've found cornerstones to help immensely.

I sash individual blocks --- leave some plain as you'll sash only one, two or three sides of those -- and use cornerstones. I prefer*not* to use long strips of sashing as I feel it sort of throws off the evenness of the piecing, sort of like leaving some areas unquilted and other areas densely quilted.

i agree... and i like the look of the cornerstones, also.

This quilt-along shows very good instructions for sashing

That's how I do it too; sometimes with cornerstones, sometimes not.

This is what I have done. Also I will sometimes add a square to go under the vertical sashes and sew a strip the size of the block end. I hope this makes sense.
