Yes, this means you have to stick with me through facts and figures (or, you know, just scroll down to the piccies). Before anything else I had to start with measuring allt he emblems, appliques or focal images on all the garments to find out what the average size was and what sort of block would work best. Fortuantely, there were only two very small images and only two very large ones, and the rest all worked themselves happily at about 4.5" square.
You should be able to see in this image the template plastic, marked with centering lines from each corner, over the image of the house:
Of course, part of what takes so long is my underestimating how long it will take to cut (and fussy cut!) that many 4.5" patches. 42 blocks, plus one for the back means over 300 patches. Oy.
An additional element of difficulty comes with handling infant and toddler clothes: there's not always that much real estate, fabric-wise. There's quite a few patches that were cut so close to the edge the seam allowance includes the stitches of cuff or ribbing.
One of the basic things I tell all beginning sewistas is to always pin more than you think you need to. Because you really need to.
It was absolutely worth it in the end:
Having so many different fabrics makes an all-over stitching pattern preferable, as it unifies the top, across all the various colours and textures. Rather than a stipple or loop that goes all over everything, we went with a traditional diagonal within each block, excluding any appliques:
The texture on the reverse actually makes me giddy - It's a delight to behold!
