Over the summer, my sister in law and I decided to work together on a quilt for our friends who were having a baby. This incredible R2D2 quilt was the result of that collaboration. It was the first time either of us had used the pre-printed interfacing grid and we were both shocked at how quickly it seemed to go together.
While visiting my husband's family over the summer, I made a stop by Sew Special Quilts in San Antonio and was buying more of the grid interfacing. They asked me what I used it for, and as luck would have it, R2D2 was in my car as he was getting delivered that evening. They hired me on-the-spot to teach a class on the grid interfacing technique. Ps: Link to the class info is over here. This is the little table topper sample I made for the class out of two mini charm packs in Moda's Fragile.
And this is the version pieced with the pre-printed grid interfacing (sooo many seam lines).
Now I had to compare the two. After endeavoring to finish them exactly the same: same batting, same backing [only in different colorways], same binding [differing solid colors], both all in the same brands of solids, and quilted with the same brand/weight of thread in as close to the same places as I could manage, differences emerged. Here is a compilation of the differences I observed both throughout the construction process and after finishing.
So basically, they are both great techniques, and like everything in life, they both have their own quirks and problems. I am not willing to say that one technique is better than the other, because it simply depends on what you are looking for, and what your preferences are.
