Hi Pam,
The blocks are looking good.
Ok the last photo is the lavender - I loved the look and feel of the material...BUT the flower print - every needle stitch shredded the material - it stretched something fierce and wouldn't work with my sewing machine or serger...so I'll be re-doing it.
The lavendar flower print is probably not 100% cotton. For this type of fabric you should probably think about getting a very lightweight fusable interfacing. Fuse to the fabric, then proceed to cut and sew the block together. You can sometimes tell if a fabric will ravel at the ends by testing it in the store by pulling against the cut edge. (Not so nice to do, but better than buying difficult to work with fabric.)
