mine is as big as a queen sized quilt :D:D:D

Mine is a 96" X 96" warm and white tacked onto a wall in my bedroom. (the only wall available as I live with my kids and can't use walls in the shared areas). It's nice to look at in the various lighting that occurs during a 24 hr period. LOL

What Great ideas you are all sharing with me. They are appreciated.

I also tack a large piece of flannel to a wall...Works for one block or the whole shebang.

I am curious so will ask? The flannel will hold fabric to it for a display board?

So I'm told but I haven't tried it yet which is why I was asking about the size. Another question: How long do the pieces/blocks stay up?

8 feet tall x 12 feet wide...used (3) 4ftx8ft sheets of 1" foam board, covered with 108" wide white flannel, adhered to wall side by side with double sided tape. so mine is as big as my wall...would be bigger if hubby would let me come down the hall ;)

My current project has been on my wall for 3 weeks, and will probably stay indefinatly.

I had the blue insulation sheets attached to the wall. They were great. I tended to use them for a bulletin board for unfinished projects. I really enjoyed seeing what I had in the works. It helped remind me I needed to finish a few before I dive into new patterns. I also find myself reaching for my 1/2 piece of blue insulation so I can use it near my sewing machine.
I used straight pins to attach what I put on the board. I didn't cover the board with anything so I don't have experience with the flannel or batting coverings. I have read on other posts that the squares tend to fall (with time) depending on their weight.

If I run my hand over a block it stays there unless I have my fan on too high. I sometimes stick a few pins in here and there especially right now as I have 5 rows of blocks up on my board right now. 4 in each block. Just have a few stick pins put here and there.
