– Needles marked 100/16 are best for heavy fabrics like denim.
– Pressing the seams open will decrease the bulkiness of the seams so you don’t have thick ridges in your finished quilt.
It’s always a good idea to lay your blocks out somewhere like on a floor or a design wall to test out your layout before joining your blocks into rows.
Once you are happy with your layout pair your rows into sets of two, then proceed with sewing them. I put wonder clip on the blocks to hold them together.
