I have made many around the world quilts & I think they are the easiest to do. I graph & color my quilt & match the fabric with the color #. I take my graph & take the pieces & stack in order til I have one strip stacked. I # the top & go down the row til I have all the strips stacked in order. I then take & sew a diagonal thread across the top outside corner of the first square. Thsat lets me know that that is the 1st strip & add to the right of the thread. then I sew all the squares for that strip together leaving the # on the top square. I continue sewing the strips, laying them on the bed so I can see that the pattern is true. When I am done sewing the strips, I then take 2 strips & sew together. then add 1 & so on til they are all sewed together. I then snadwich & tie my quilts. I haven't attempted to quilt one of the big ones yet. I cut my #'s from old calenders & usually use 19 #'s for a large king to the floor. I use the back to come over the front & topstitch down after it is all tied. I also double sew my squares together going 1 way then the other. I do the same with each strip. sew down then back up from the bottom. I have never had a quilt come apart at the seams using this method. It can be washed a thousand times & should never come apart at the seams. I use more thread that way but also no embarrassment of having to put it back together if it comes apart. Just my way and have done ever since I started and wouldn't do it any other way.
