Part one of the series. Entrelac Crochet Blanket. This will be a crochet-along. Follow the link in the annotations to the next video.
The formula to figure out how many chains to make is to Make 10 chains for each beginning square add 1 chain for each square (for the chain that joins the squares together. ) Minus 1 chain. (There is one less join than there is squares. )
Example: 3 starting squares: 3 x 10= 30. 30 +3 =33. 33-1=32. so chain 32 for a center of 3 squares.
"Can you make bigger squares?" has been asked several times, so here is the answer to that question:
"...you could make it twice the size and do 21 chains for each square. Don't forget to add the chains that go between the squares. ...Bigger squares would mean you could cross-stitch onto them too! (corrected this 6/6/13)
Here is a suggestion from a viewer, Wanda Brayboy: Hello everyone. As I was watching this video series for the second time I discovered a little trick that will lessen and/or eliminate the "bulkiness/roll" from slip stitching up the side of the square. When slip stitching, insert your hook into the outer loop only. This makes the slip stitches lie flatter. This should lessen your work during the blocking process at the end of the project as well. Hope tip helps you. Happy crochet.
