I am making a crumb quilt and want to set my squares on point. There is a lot of help out there for figuring the corner and side triangles, but I also want to add sashing. One site said to add the width of the sashing into the block... ok I may be pretty dense here.... there is sashing on each side of the block. Do I add each side or only one? Any help any of you can give me will be greatly appreciated. Quilter1234

Add sashing on 2 sides - except on ONE of the outside rows where you'll have to add it on another side. Try drawing it roughly on paper, and you'll understand better.

You can see that the sashing is added to the sides of each block (pink) and then long strips of sashing (green) are then added after the row of blocks are sewn together.

This is a very good question & I
think that Amma has showed all
of us, a good example!! Thank
you Amma.
:D :D :D :D :D

so do I add the width of the pink sashing to the size of my block.

Example .. block is 6 inches finished, sashing is 2 inches finished, therefore I consider by block as an 8 inch block and figure my corner and side triangles accordingly.

Thank you for your diagram and help with this. Quilter 1234

My problem is figuring the corner and side triangles... I guess I didn't make that clear... not about the sashing really... sorry for the confusion. quilter 1234

No...look again closely at the picture posted...the blocks are still the 6"..the sashing is just what it is..2" sashing. When you figure your corner BLOCKS and side BLOCK triangles...they will correspond to your block measurement. I'll tell you who can tell you exactly what size to do...Patrice...she is the goddess of this one!! Ask her.. :lol:

Quiltville has several helpful tables for figuring out different types of things, like on point settings, backing sizes, etc. Here's the link: http://quiltville.com/onpointmath.shtml

Thank you , I had seen this site... it is the one that says you should had the width of the sashing to the block to figure size of corner and side triangle.... it's way at the bottom... girls.... I am so confused... am I making this too hard. Quilter 1234

Exactly! And that's just what the quiltville site says. It's quite simple really, if you don't over think it. The finished width of the block (6") + the finished width of the sashing (2") = the finished width of the sashed block (8"). You figure the setting corners and triangles using the finished width of the SASHED block.
