OK... Now comes out some math! I don't have a handy program like EQ7... I'm new to quilting, but do have a math/science background. So first I start with a Google search, I find a few tools, but nothing really what I was looking for... I need to figure out the sashing requirements for a bunch of 12-inch blocks (12.5" finished).
Some assumptions for my calculations:
- We get 25 blocks
- Sashing/Border is 2" Finished
I found this interesting tool:
My Web Quilter. I was able to design this quilt... With the information I put in, it was able to tell me that the quilt was 72" square... and then by selecting "Pattern" I was able to get some more information...
My Web Quilter is a basic program, but for those of us that don't have access to a more advanced program, its very helpful! And helped verify my calculations I did on scrap paper....
Vertical Sash
Fabric Required: 1/2 YD
Finished Width: 2.00 (IN)
Cut 7 (2.5 IN) strips. Cut 20 pieces of size 12.5 by 2.5 IN
For all blocks, except those in the left most column, sew vertical sash pieces to the left side of the each block.
Sew blocks into 5 rows with 5 blocks in each row.
Horizontal Sash
Fabric Required: 1/2 YD
Finished Width: 2.00
Cut 7 (2.5 IN) strips for the horizontal sashing.Construct 4 horizontal sash of size 68.5 by 2.5 IN
For all rows except the top most row, sew a horizontal sash strip to the top of the row.
Sew rows together according to the quilt diagram.
Border 1
Fabric Required: 1/2 YD
Finished Border Width: 2.00 (IN)
Style: Solid Fill: Black
Expected quilt dimensions before adding this border: 68.5 by 68.5 (IN)
Cut 7 (2.5 IN) strips of the border fabric.
Construct 2 strips for quilt length (68.5 by 2.5) IN
Pin and sew borders along length of quilt.
Construct 2 strips for quilt width (72.5 by 2.5) IN
Pin and sew borders along width of quilt.
Backing
Approximate fabric requirements for backing: 4 3/8 YD.
Construct 2 strips the width of the fabric and length at least 78.5. Sew strips together to form horizontal seams in the backing.
Binding
Fabric required: 5/8 YD. Cut 8 strips of width 2.5 IN.
My calculations on paper got that I required 55" so I would buy 1-3/4 yards... This calculator says I need 1-1/2 yds for the sashing and border. I think I'd still buy 1-3/4 yds to ensure I have enough....
As for backing, when I gave the estimate to someone earlier, I think I under estimated because I forgot about the sashing... According to the same calculator I'd need 4-3/8yd. No problem if I'm short, as I'll just add a strip of something coordinating or contrasting... or possibly some extra blocks...
