Floor Blankets...Help!

Looking for cute blankets to lay on floor for baby. With 2 dogs I definitely don’t want her directly on our rugs or carpet.

No clue what this is called to search for it online.

Don’t want those crazy jungle mats and that’s all I see when I search.

Just want a few beautiful, soft, silk-like material blankets I can lie down and wash often.

Would like it to be like this kind of material in the picture.

Help please!

Anyone know who sells something like this or anything? And what is it called?
