I'm making a MAXI quilt out of MINI pieces. 200 blocks, over 2000 pieces ... a good deal of them are 1" cuts. And one of my bucket list projects (high on my list) is a mini pineapple - I was so inspiried by the Mini's I saw at the AQS museum. Got to try those!!
Some tips ...
Highly suggest pre-washing/drying especially if your working with fabrics from different manufacturers. With pieces that small the difference between 1% shrinkage and 1.5% shrinkage is going to greatly affect the finished block, and if you didn't pre-wash - you may not like the uneven shrinkage through the whole quilt.
STARCH! LOT'S AND LOTS OF STARCH!! I starch my fabric prior to cutting, and I starch each seam. Each of my blocks had been starched several times. The starch will help you keep your cuts straight and your seams even. When I started the project I didn't starch, then I "discovered" the benefits from the great people on this board and the ease of work and improvement of uniformity was dramatic.
Don't settle for "close enough" with your seam allowances. Every little bit will translate through the quilt.
Don't settle for "close enough" when matching seams either. See above.
Along the same line as above ... try not to have too much variation in the fabric that you choose. For example, Batiks are much lighter in weight and thickness than an Asian print for example. The problem with this is that your accurate 1/4" seam allowance is going to be different for every combination of different weights that you are using. Asian seamed to batik will require a different "scant 1/4" than a Batik to Batik.
Check the size and square with every seam. Honest.
Yes, it's a lot of work but I personally find it very rewarding to work with.
Have fun!!
