I recently purchased my first kit. And the pattern was a separate purchase. I guess that I did not find it curious. I found that the kit saved me from having to figure out the fabric for this particular project. Easy. I don't understand the need to substitute fabrics even if i may not care for one or two. They compliment the others, but that is me. I paid for convenience.
yes, the shop should "remind" the buyer to purchase the kit pattern. Perhaps this assumes that the buyer may already have the patten, otherwise? Hmm....multiple kits...1 pattern needed? I dunno.
