LPN, Annabelle is a very pretty evenweave that looks like a shinier linen. As we've said, for evenweaves, linens, count threads & you stitch over 2 threads, leaving you with 1/2 the number of x-stitches per inch. Exactly 14 for Annabelle 28, same as your piece of Aida 14-ct, but not nearly as pretty.
Count Holes: Aida. Count threads: Evenweave, Linen.
A 28-ct Aida, if it existed, would be like a 56-ct evenweave. We're talking "silk gauze" here, or earning stars for your crown in heaven.
Gotta go! Need more coffee.
