Comet Quilt VI – The Back

All those bright blue triangles I had leftover when I remade so many of those HST blocks? I used them to make more HST blocks for the insert on the back of the quilt!

25 of 125 blocks

The quilt top is 54″ x 68″. I need to make the back 4″ larger in both length and width: 58″ x 72″ or thereabouts (I’ll be using the off-cuts to do a hidden binding after the quilt is quilted). My HST blocks finish at 3″ so I needed 25 of them for the length (one extra row just in case), and 5 blocks for the width (15″ to make the back panel wide enough: 42″ + 16 1/2″) will do it.

I needed 125 blocks to construct the insert strip. The strip will be bordered with two dark strips – a finished 1″ strip using the last small scraps I had of the Sparkle fabric (not a single bit left), and one other (finished width 1/2″) yet to be determined!

I have assembled two of the 25 blocks elements – 3 to go. I should get those done today. Tomorrow I’ll put the quilt back together, set up the sandwich and then think about what kind of quilting design would complement the Comet Quilt top – no idea about that yet.

Shadow Quilt – Quilt Back


I started this insert for the Shadow Quilt back by cutting 2 1/2″ strips of the fabrics used on the top and sewing two strips together. At that point I wasn’t sure what I would do with the double strips. I ended up cutting equilateral triangles, sewing pairs into diamonds, then compiling four diamonds into a larger one.


This large diamond gave me 9″ for the start of what I intend to be a 14″ strip.

I aligned five large diamonds end to end: 75″ – long enough for the quilt back but I wanted to fill in where the points touched. I added single small diamonds on each side in the space. That still left ten half-diamonds needed on each side. The easiest way to figure out the dimensions for these half-diamonds was to place a sheet of paper beneath the diamond layout and draw in the missing half-diamond (I added a 1/4″ to each angled side to be sure there would be adequate seam allowances).


I did the same for the 1/4 diamonds needed to complete the ends as well.

Now diamonds are pieced in diagonal lines. Because I was improvising as I went along, I already had the large 4-part diamonds sewn which complicated the process somewhat. In the end I laid out the pieces and assembled the strip section by section.

Width so far: 9 1/4″ – so I’ve cut strips for each side:


The borders: 1″ red, 1/2″ dark grey, 2 1/2″ light grey on the outside. The strip will be inserted into the darker grey fabric with vertical pale lines and dots.

I’ll add the borders tomorrow.
