After wishing for crochet cotton that is larger than number 10, I found some about equivalent to sport or worsted weight yarn ,  numbers 3 or 4.  Premier Home brand, which is 85% cotton, and 15% polyester.

  And thereafter, I indulged in making several dishcloths, which are popular to make now.    The top rainbow-colored one weighs 1.4 ounces, and has a nice feel wet.  It also looks nice, with the only detractor being the that the rows in the middle make the edge gather up, due to the fact that I double crocheted in the chain one space between the previous rows.

  For this one I tried, unsuccessfully, to pick a complementary color for the square to go with the leftover yarn from the cloth. This time I crocheted in the top of the double crochet of the previous row, and it does have a nicer edge.  The detractor here in addition to the edging not harmonizing in color, is that the edging is too big, being a repeat of chain five, skip two chains, and single crocheton the first edging row.

 Here I show a solid blue dishcloth, which I purposely made a little smaller, inspired by a Premier Home free pattern.  The weight of this one came out to be nearly exactly one ounce.    This lower weight does not give as good a feel in the hand.

Conclusions:

1. Be careful withe mixing rows of double crochet in to spaces made by chaining one in the previous row, if the same row also contains double crochet into double crochet.

2.  Rainbow multicolored yarn does not look good outside of maroon solid colored yarn.

3.  1.4 ounce dishcloths feel better wet in the hand than 1.0 ounce dishcloths.
