I vote for the last one.

I love snuggle quilts with everything going every which way. But with a wall hanging, I think they need to be right side up. Adding sashing as needed will get them all the same size.
Have fun.

I have seen some beautiful Tshirt quilts. They used stabilizer and it gave the knit shirts much more body. I personally hate looking at anything that I have to look every which way, I prefer things in a more orderly direction (yes, I am a Libra). I would use sashing to make the blocks it.

I have made four bed size t-shirt quilts. They look better when they are uni-directional. A sash for each block really helps to off set each t-shirt. I used the school colors as sashing for my son's t-shirt quilts. Also, for the stablilizer, be very careful when choosing. The first t-shirt quilt I made, I used an iron on fabric and it made the quilt very heavy, plus gummed up the needle very badly. For the t-shirts that are an irregular size, either cut down to fit the others or fill in with another fabric so the blocks are similar in size. just my 2 cents! Good luck with the quilt :)

I'm with you, I like #3. That would be my first choice, then #4. I have done t-shirt quilts and I have found that the quilts I've done with the t-shirts all the same direction framed and then another background fabric, are wonderful. But the ones with the t-shirts in all different directions are fun and feel like they can be used, washed and loved. So I think just like any other quilt we do, it's up to you, your DD and how you both think her friend will use it. Good Luck

The girl may have no idea how it's going to turn out, and once she sees how big it is, I'm sure it will go on her bed or couch. I love that picture of the one with the printed background and various size/shape blocks. In any case, I agree with all-one-way opinions. You are a good mom to do this for her, and I'm sure it's fun to do it.

I totally agree with Barb in Louisiana so I guess that makes me old too. I love the one that she displayed. It's neat, organized & easy to read. Obviously, it's up to the one who is paying you but IMHO, I agree with Barb.

I've made a lot of tshirt quilts and they have always been hits. I do keep mine one directional, for ease of reading, and I frame the blocks to bring them to size.
I keep as little of the actual knit fabric as possible, trimming around just the design. I tend to like scrappy framing for each block then I use a common fabric to sash the quilt. I like to use even the small designs, and will often join 4 of them to make a block to equal the larger blocks. Or I might use a long narrow section to add size to one that is shorter by adding it to the top, bottom or side.
I make each row like a puzzle, and it may be taller or shorter than another row. I just make them all the same width so they fit together across.

Me too, I like the last setting. Great quilt.

I am with Barb in Louisiana - I like them all going in the same direction.

Of the 4 options you showed, I like #4 the best.
