I have what some might call a despicable habit of seeing words within words, like spotting the COP in SCOPE or detecting the ART in GARRETS, but the habit is recreational. Noting in the latter that the inner word was spelled with the letters in the even-numbered positions while the odd letters GRES did not form a common word, I began looking for "woven words" for which both the even and the odd groups were interwoven words.
