For someone who is not into novelty or floral fabric there sure is a lot of it. Okay which fabric fairy put them in the stash and let them multiply!? What to make out of the Hallowe'en fabric? See how well the 1 meter pieces blend together. This has to be a 2 fabric quilt because the fabrics are so busy. Now, what color to use for the second fabric. Lime looked good but liked the way black made some of the Hallowe'en fabric float. Use not 1 black but many blacks.
Next, which block(s) to use. Let's make it simple. Squares vs triangles. Triangles more work but way more interesting. Quarter vs half square triangles. Okay, half-square triangles easier. What size triangles? Trail and error with the ruler. Don't cut just audition size. 3" looks good.
Size? A large lap / not so long twin size quilt, about 60" x 75", is just right. Doesn't take so long to make, isn't huge, lots of room to snuggle under. Finished 12" blocks = 5 x 6 block quilt : 1 block = 16 half-square triangles : 30 blocks = 480 half-square triangles, OMG = 240 squares cut from each of the 2 colors (hallowe'en and black) cut into triangles and well stirred. The 60mm rotary cutter works well for mass production.
Well, this got me out of reorganzing. Now to dig out the sewing machine from under the reorganizing. LOL!
