It really is simple.  I made up a fancy diagram in Excel but can't figure out how to get it posted here and didn't want to take the time to design it in EQ 7 so instead I'm just going to list the steps.  I didn't take a ton of pictures during construction as it was just sewing the bricks end to end but I think you can figure out that part easily enough. 

To make your own version you will need:

(1) 5" x 5" charm for the trunk

(53) 2 1/2" x 5" bricks in your choice of colors and prints

(9) 2 1/2" x WOF White strips

(2) 5" x 16" White strips

(32) 2 1/2" x 5" bricks for the binding (if you choose to do it the same)

 42" x WOF of your choice for your backing (I used White muslin)

Note: All pieces listed below are CUT sizes, not finished size.  For your White strips cut the longest pieces first and use the leftovers to cut the shorter pieces.

You will be just sewing the pieces end to end using a slight 1/4" seam and pressing all seams to one side. I pressed the Red seams to the right and the Green seams to the left so that when they did meet when sewing the rows together, they butting nicely.

Assemble your tree rows first but do not sew the rows together at this point.  After you sew all your tree rows you will want to measure YOUR pieces and adjust the length of your White strips accordingly to achieve the correct desired width.  Mine quilt is 36" wide.  

The tree row cut size pieces are as follows, placed from left to right:

                          Row 1:  (1) 3" brick

                          Row 2:  (1) 5" brick

                          Row 3:  (1) 3" brick and then (1) 5" brick

                          Row 4:  (2) 5" brick

                          Row 5:  (1) 5" brick, then (1) 3" brick and then (1) more 5" brick

                          Row 6:  (3) 5" bricks

                          Row 7:  (2) 5" bricks, then (1) 3" brick and then (1) more 5" brick

                          Row 8:  (4) 5" bricks

                          Row 9:  (2) 5" bricks, then (1) 3" brick and then (2) more 5" bricks

                          Row 10:  (5) 5" bricks

                          Row 11:  (2) 5" bricks, then (1) 3" brick and then (3) more 5" bricks

                          Row 12:  (6) 5" bricks

                          Row 13:  (3) 5" bricks, then (1) 3" brick and then (3) more 5" bricks

                          Row 14" (7) 5" bricks

                          Row 15:  (1) 5' x 5"  charm

Once you've completed the rows for your tree, then you will need to add the White 2 /12" wide strips to both ends to complete the background.  The cut sizes for the White strips are as follows:

                                                 Row 1:  (2) 17" strips

                                                 Row 2:  (2) 16" strips

                                                 Row 3:  (2) 14 3/4" strips

                                                 Row 4:  (2) 13 3/4" strips

                                                 Row 5:  (2) 12 1/2" strips

                                                 Row 6:  (2) 11 1/2" strips

                                                 Row 7:  (2) 10 1/4" strips

                                                 Row 8:  (2) 9 1/4" strips

                                                 Row 9:  (2) 8" strips

                                                 Row 10:  (2) 7" strips

                                                 Row 11:  (2) 5 3/4" strips

                                                 Row 12:  (2) 4 3/4" strips

                                                 Row 13:  (2) 3 1/2" strips

                                                 Row 14:  (2) 2 1/2" strips
                                                 Row 15: (2) 16" x 5" wide strips

 Once you have all your rows complete just sew them together, matching up seams where they meet. Lastly add (1) 2 1/2" x 36" strip each to the top and the bottom and your quilt top is done.

Quilt however you wish.  To make the binding, again sew the 2 1/2" bricks end to end using a slight 1/4" seam and press open.  

Your result will be a 36" x 36 1/2" quilt you will be proud to hang in your home for all to admire and enjoy.

I'd love to see your own versions of my Jingle Tree when it is done so please share.
