I Did Some Research
 

I did some research for asking this question. I would like to make a puff/biscuit quilt. I've watched several YouTube tutorials (see below) and went in about five pages under the search option of this site. I understand that you cut your base square smaller than your top square. I would like to use flannel as the base square. I'm wondering if it will become too ragged between the seems of the top by using flannel when joining the blocks? All of the info I've seen says that the base square will not be seen, but I'd like to incorporated as part of the backing design. Is this possible? Please help or redirect me...thanks!

when I made mine YEARS ago, after the squares were put together, you then put a lining on the whole bottom, I guess you could leave that off but I would worry about handling the flannel that much.

Becau the flannel would get "stringy"? Sorry, im
still a beginner with too many ideas.

There may be a method that I'm not aware of, but when you piece the individual bicuits together, you are left with raw edges of both the top and backing fabric on t back of your quilt. You can't just leave this because they will ravel (get stringy). I think the only alternative I can think of is to make the joining seams about half an inch, then make perpendicular clips so you would have a sort of rag quilt on the back.

Avery long time ago,my auntie would sew 2 squares of fabric together and put a rolled up nylon stocking inside,then sewing the blocks to each other.

Could you just do it the regular way and use flannel for the backing?

Puff quilts are really fiddely and I would not care to add more challenge by using a ravelly flannel. Why don't you use flannel on the back?

I'm now looking for a scratch fabric I can use as a liner. Any other ideas or suggestions?

I made a puff/biscuit quilt about 6 months ago. I used some inexpensive muslin for the scratch fabric - worked great. I used minky as my backing and put it together using the "birthing" method. Flannel would make a good backing, too!

I made two puff/biscuit quilts a long time ago. I used a backing for them and tied it with pretty ribbon at each seam You could use flannel as your backing. These are heavy quilts when finished with all the stuffing in each biscuit
