Ok sooty it took me so long to reply...
The second one is a snail trail take a detour. I used wee woodland and Bella solid jelly rolls. It was an all nighter class.
The third one is called spider web (I think) and I used 3 Hello Betty honey buns. It called for jelly rolls and you use 3 strips but I used a honey bun with 5 stripes. So it would be about the same size. I put them into strip sets and then used a 60 degrees angled ruler and cut them out and then connected the 3 wedges so its a half hexagon then sewed rows and had to work on two rows at a time so other half of hexagon would line up. It was fun just very tedious with sewing all the strips.
Thanks for all the nice comments.. let me know if there are any other questions....
