20. Open the blocks back up and they are now joined together.

21. Stitch all blocks for the row together like so. I'm using 5 blocks in this row.

22. Now, we need to stitch down the points in the middle of the block. But, we only want to do that for a point that is on the INNER portion of the row, NOT the OUTER portion. Remember, you still have to join this row to other rows and blocks, to those outer points need to remain loose until you do that. So this pic shows me taking down just one point on the end block.

23. On the middle 3 blocks, I'll tack down two points.

24. Row with the inner points all tacked down now. One on each end block, and two on each of the 3 inner blocks.

25. We now have 4 window blocks ready for installing the glass. Below is a pic of my window glass fabrics.

26. To determine the size of your window glass fabrics, measure across the window area. On my 4" blocks, the diamond shaped window area measures about 2.75" across. I like to make my glass about 1/8" less all the way around, so I cut my glass fabric in 2.5" squares.

27. Here you can see the glass fabric layout in the window frame, about 1/8" smaller than the window frame fabric.

28. Now comes the fun part! Roll the edge of the window fabric so that it lays over the glass fabric by about 1/4" at the middle of the roll. You can see that it tapers to a point at each end.

29. Beginning at the point, use the presser foot to help hold the roll of fabric flat and in place and set you needle down into the point. Use a backstitch to anchor the stitch.
